Worse yet, the Ubuntu security incident page[0] lists "Ubuntu Priority: High" (as opposed to Critical, which would trigger an out-of-schedule patch). There's a "Why this priority?" link that simply says:
> Why is this CVE high priority?
> See ubuntu cvss score
That's it, we don't even get a period on this TBD of a sentence. It's followed by a generic link that explains what "Ubuntu Priority" is, but that page contradicts their choice. Note that it doesn't offer any mitigations either, and even the (horrendously unclear) description is copied from the NIST page, so there's no actual message from Ubuntu.
I already had a bad feeling the first time I saw "Get more security updates through Ubuntu Pro" on `apt upgrade`, this is now the kick I needed to move to a different distro.
Yeah, their lack of a satisfactory response is the final nail in their coffin. This incident escalates my consulting advice about Ubuntu from “not recommended” to “switch immediately”.
Some of my clients may be surprised by this change, as I once advocated for Ubuntu as a good choice for a development and deployment platform. While that has not been true for quite a while, they have now jumped the shark into eel-infested waters; I cannot take them seriously any longer.
Not always. Notably, if you have compliance requirements like needing FIPS encryption (say because you have government customers), or that requires you to use a commercial vendor, debian won't work. And if you need more up to date system packages, or a reliable release cadence, Ubuntu might be better.
On desktop, if you need proprietary drivers, Ubuntu is easier to set up.
But yes, if debian works for you, I wouldn't use Ubuntu.
It doesn't have much to do with this CVE, but if you're trying to sell to the US government, it will often be a requirement, which means that a company making money from those sales will not easily be able to move to a distro without that certification.
It isn't a validated build. It works the same, but it isn't sufficient if you actually need a validated FIPS module.
> It's just the library, nothing special about the OS.
If you need validation, then the kernel also need to be validated.
Now, it isn't impossible to get a FIPS validated system working with Debian, but you will probably need to contract with another commercial provider like WolfSSL to get validated components. Or compile things yourself. But that is more complicated and involved than just paying for an OS that is validated off the shelf from Ubuntu, Red Hat, or Suse.
The general advice I've been seeing the past ~8 years is "There is no reason to pick Ubuntu over Debian". I don't know who the opposite advice comes from and why anyone would pick ubuntu for a server.
15-20 years ago the joke was that Ubuntu is a Zulu word that, roughly translated, means "I don't know how to configure Debian". Ubuntu was one of the first distros that allowed one to easily download proprietary WLAN drivers without dealing with the terminal, ndiswrapper, or compiling half-broken OSS implementations; for this reason it caught fire with those who wanted to try Linux but were otherwise unwilling to engage in such shenanigans. I tried it on a laptop around this time and was quite impressed. This reputation for "it just works" has carried them ever since even though other distros now do largely the same thing ( cheap, obscure, or recently-released hardware excepted).
I took the lazy Mint route with my most recent machine since I wanted to use it for light gaming with minimal fuss. I'm going to redo it with Nix sometime soon because the value prop simply isn't there and I'd like to try a declaratively-configured distro.
The only recent reason I’ve managed to come up with is it far and away has the best support for Nvidia’s various drivers and utilities for running GPUs and its assorted ecosystem, like Infiniband and Spectrum-X Ethernet.
If there’s another option I’m unaware of, I’d love to hear it. Also to be fair, I didn’t evaluate Sid for this, only Stable.
Enterprises love paying for support contracts. If you have one, you can demonstrate something has been accounted for. A secure software without support is worse from an audit perspective than a security disaster with proper paperwork.
Most of these people never actually involve support they paid for ever.
They can pay for Debian support! (I’m not 100% sure who they should go to, but e.g. Freexian are doing Extended LTS for Debian [1], so I suppose they could do a regular support contract as well?)
I advocated for Ubuntu for years because it was easier to install and had excellent hardware support. For 2026 I have switched back to Debian because Ubuntu has been making my life more difficult. Ubuntu 26 basically forces you onto Wayland even though it breaks some of my use cases, particularly with screen recording. It turns everything into Snaps which is a hassle because it means I need to mirror both the regular repo and the snaps to my closed network instead of just the repo.
Ubuntu still has the superior installer by a good margin, but it does sometimes like to crash when run offline. Debian's installer at least has the option to go text only. There is also more work to do after the install is finished on Debian, but since that's a script it's not such a big deal.
The one bit of the Debian installer I dislike the most is how if you aren't online when you do the install you get a completely empty sources.list, and the Debian sources are a lot more complicated than Ubuntu's. Debian's support for third party drivers like nVidia graphics is also more complicated and confusing than Ubuntu's.
Platform support. Oracle Cloud for example only provides images[1] for Oracle Linux, RHEL, Ubuntu, and Windows Server. Anything else you have to bring your own.
If I try to create a new instance on Oracle Cloud, these are the options: Oracle Linux, Ubuntu, RHEL, (CentOS), Windows Server, AlmaLinux, Rocky Linux.
Anyway you are right, I would have switched already if Debian was available. I guess AlmaLinux could be an option to consider, since I've read in another comment that they've patched ahead of upstream for several vulnerabilities this year.
For x86_64, It's relatively easy-ish to upload your own Debian image, from Debian's generic cloud QCOW2 image, and it works just fine. I think ARM needs a bit more work if I remember correctly.
As far as I know the only working exploit is working on machine with MultiTCP enabled. Redhat also downgraded the issue to "high" and also did not release a patch yet. I would have preferred a patch but I accept that they know better than me what they are doing.
Moved to Debian few years back and never looked back. We used Ubuntu for a bunch of clients and unfortunately had to let them know they will have to migrate to Debian or similar. It's such a shame because I really used to love Ubuntu until Canonical started turning slowly into your typical everyday corporate.
The more I look at this the angrier I get. This is a CVE that Anthropic claims can get a Remote Code Execution on vulnerable systems, which includes default Ubuntu installs running any sort of Go server like Caddy. Bad enough that I shut down my personal website and self-hosted tools (sorry for any typos, my grammar checker is also down).
And this is how Ubuntu describes the vulnerability to sysadmins:
In the Linux kernel, the following vulnerability has been resolved:
ipv4: free inet_opt and ireq_opt after an RCU grace period
tcp_v4_syn_recv_sock() transfers ownership of ireq->ireq_opt to the
child socket (newinet->inet_opt) without copying it.
Another cpu can concurrently process a retransmitted SYN for the same
request socket, and send a SYNACK from tcp_check_req().
tcp_v4_send_synack() and inet_csk_route_req() read ireq->ireq_opt
under rcu_read_lock() only, and ip_build_and_send_pkt() and
ip_options_build() then read opt->optlen twice.
Note that the SYNACK timer itself is not an issue: it holds a
reference on its request socket, and inet_csk_reqsk_queue_drop()
calls timer_delete_sync() before the child can be freed.
Since commit 079096f103fa (“tcp/dccp: install syn_recv requests
into ehash table”), request sockets are processed without holding
the listener lock, so nothing prevents the child socket from being
freed while the SYNACK is still being built. TCP child sockets do
not have SOCK_RCU_FREE, and inet_sock_destruct() frees inet_opt
with a plain kfree(), leading to a use-after-free in
ip_options_build().
A similar issue exists with request socket migration
(net.ipv4.tcp_migrate_req=1, or a BPF_SK_REUSEPORT_SELECT_OR_MIGRATE
program). reqsk_timer_handler() clones the request socket with
inet_reqsk_clone(), so that the old request socket and its clone
share the same ireq_opt, then reqsk_migrate_reset() clears the
pointer in the old one. Another cpu holding a reference on the old
request socket can still be using these options (sending a SYNACK,
or creating a child in tcp_v4_syn_recv_sock()) when the clone is
freed, and tcp_v4_reqsk_destructor() also uses a plain kfree().
Readers already use RCU, and other paths replacing inet_opt
(do_ip_setsockopt(), cipso_v4_sock_setattr()...) already use
kfree_rcu(). Use kfree_rcu() in inet_sock_destruct() and
tcp_v4_reqsk_destructor() as well.
IPv6 is not affected by the first issue, because tcp_v6_syn_recv_sock()
duplicates the options. tcp_v6_reqsk_destructor() has the same
migration issue with ipv6_opt, which is only set by CALIPSO. This
will be addressed in a separate patch.
How is this in any way, shape, or form acceptable two weeks after the CVE was published?
It's so much worse than this, and there is a staggering amount of misinformation running rampant about this bug.
MPTCP is not a requirement, it can be exploited merely by sending specially crafted TCP packets with (any) IP options set. No special MPTCP support, web servers or any specific software listeners are even necessary at all to trigger it, just send the packets and boom.
I think the reason people assume MPTCP is a requirement is because that's what the PoC used... but MPTCP itself also doesn't even rely solely on IP options.
Ubuntu also does not even list a single mitigation strategy... at least RHEL did.
And like I said, any normal TCP packet that contains IP (not TCP) options can trigger the bug. I cannot emphasize enough how important and absolutely ridiculous this is.
Like the post says, this is big enough to get a massive amount of people to completely stop trusting Ubuntu entirely and jump ship.
sorry for any typos, my grammar checker is also down
I assume this is unrelated to the Ubuntu situation, but how does a grammar checker go down? We've been doing offline grammar checking since computers had 64K of RAM.
Self-hosted LanguageTool server[0] with browser addon. 18 gigabytes of n-gram data plus machine learning models. You can catch tpyos on 64K of RAM, but not any deep grammar mistakes, un-idiomatic phrases, or mistakes in common proper names.
Your comment should be higher. Most indignant comments here are variants of "Tell me you don't know about CVE triage and Linux kernel releases without telling me you don't know about them". I mean, I also don't know a lot about them, but Canonical's security record has been exemplary in my experience, and I see no solid reason to doubt their process in this instance.
First, if this CVE did truly put every Ubuntu machine on the Internet at risk, we'd know about mass compromises by now, and there haven't been any reports. It means the CVE is not trivially exploited.
Second, the gravity of the CVE dictates the security release cycle. Emergency kernel patches carry risks of their own, and it would be worse to hurry a non-critical patch and crash a part of their massive user base.
Edit: I've been enjoying this comment going up and then into the negatives, what a roller coaster.
It’s okay to have criticism, but at least be constructive about it. This “I demand to speak to the manager” energy should be kept out of open source.
The post gives no details about what this vulnerability is, how critical it is, how it is impacting them personally, how vulnerable their servers are, how they are working around it.
Just a title designed to generate the maximum outrage followed by a few meaningless lines.
> The post gives no details about what this vulnerability is, how critical it is, how it is impacting them personally, how vulnerable their servers are, how they are working around it.
Yes it does? And Ubuntu is selling security subscriptions and doing a poor job of it, These aren't open source volunteers, this is a paid product.
I read the whole post and still don’t have any idea what it is and how severe it is. Ubuntu has not marked it critical. Is there any reason to disagree with that assessment? In an entire post criticizing Ubuntu you’d think they would at least make that case.
They have also not shared why they didn’t patch their kernel directly when updated versions have been available for a couple weeks now. Why wait for Ubuntu at all?
You are talking about the company side of the issues. We are talking about the specific issue that is concerning our ubuntu servers. What is the security bug, and how can someone exploit it? Where is that written?
It doesn't. There is just one link to the CVE. It doesn't explain the exploit nor how it works in what condition. Everything else is blown out of proportion: "I'm migrating all my servers to this other OS" and "I never liked their desktop anyway". Pathetic if you ask me, such a Karen.
Also, the author uses Claude to make 270 LoC bash scripts. I think his opinion doesn't matter.
This is a major failure on Ubuntus part. The constructive feedback they deserve is literally the title of the article.
The post gives enough detail, there is a vulnerability that allows root access on servers on the TCP stack, so literally accessible if you are running any service. There are exploits in the wild. Debian has the patched kernel, Ubuntu does not 2 weeks after the CVE is known.
> how critical it is,
9.8 out of 10 btw.
> how it is impacting them personally,
They are clearly rather upset by the lack of an appropriate response.
> how vulnerable their servers are,
They are literally open to anyone with an AI subscription.
But Ubuntu is not some small distro maintained by unpaid volunteers; they are a corporation that offers paid support. I think it reasonable to be disconcerted when a company that you are paying for security updates is this negligent, especially when other distros have fixed this issue far more expediently.
It's a large international corporation with hundreds of millions in revenue from enterprise contracts. There is in fact a manager to speak to and I do in fact demand to speak to them.
"Speak to the Manager" is absolutely the best way to summarize this. I pay nothing for your product, but don't you know who I am? I'm moving all my VPS work loads away from you!!!11!
> This “I demand to speak to the manager” energy should be kept out of open source.
This. You are welcome to publish patches and demonstrate how people can fix their own machines out of band with what Ubuntu does. This costs you... 10 minutes with AI help?
While it's easier than ever to complain this year, I'm patching all the things while on a walk or not at my computer, it's great!
>The post gives no details about what this vulnerability is, how critical it is
what? the literal first paragraph says:
"In case you missed it: CVE-2026-98432 is a critical (CVSS 9.8) bug in the Linux kernel's TCP code. It's been there since 2016, so virtually every Linux server on the planet has it, and it can be hit remotely"
I knew what this is about before clicking the link. While trying to find remediations for vulnerable systems I was also looking for any kind of "official" statement on literally WTF is going on here from the Ubuntu side, but I haven't been able to find one yet. I guess it has to go through the "hacker news puts enough attention on it for someone to care" phase which we all know so well...
Have companies been compromised because of this vulnerability? Ubuntu has an absolutely massive install base. The lack of notable incidents suggests that 9.8 might not reflect real-world well.
If someone does a v2 let's hope they make sure it's actually exploitable when they set it up so they don't leave hundreds of people with the assumption that the cve is not a big deal when the CTF was just misconfigured and the system got pwned in less than 2 hrs after they fixed it
CVSS in general is not the best proxy for "real world impact". You could have a 10 on a software thats only deployed once and the impact would be tiny. In this case, multipath is not used that much (except by go).
Go is everywhere in server environment. It's absurd to claim that multipath is not used that much. Maybe it's me, but go literally everywhere around me.
Also this vulnerability is not strictly about mptcp, although the exploitability is not clear.
But they have very valid point: a CVE 10.0 with root RCE on twenty internal servers is lower risk than one vulnerable internet-facing server. All need to be patched, but the one on the Internet is your critical risk, the others are medium at worse.
Contrast this with: "The Gift of It's Your Problem Now"
We keep doing this to ourselves. Heads should roll at Ubuntu. Start that process right now? You can't. You see, nobody is directly available to sue. It does seem that nobody ever truly cared about that. The insecure codebase and tech debt shall continue to grow because that is the gift.
I think it's less of a concern over the internet because the kind of packet necessary for the exploit tends to be filtered out, but it's pretty scary as an escalation mechanism from e.g. an end-user device to a core server.
Much like with PHP2Shell, it doesn't need to be utterly trivially exploitable to be a big concern.
I don't quite understand this page. I thought the kernel binary was in the `linux-image-` packages in Ubuntu.
For example, I have linux-image-generic installed, description "Generic Linux kernel image
This package will always depend on the latest generic kernel image
available." and then "Depends: linux-image-6.8.0-147-generic, linux-modules-extra-6.8.0-147-generic, linux-firmware, intel-microcode, amd64-microcode"
Why isn't there linux-image or linux-modules-* listed as an affected package?
First I thought it was the source package / binary package distinction, but e.g. linux-image-7.0.0-38-generic says "Source: linux-signed-hwe-7.0", and linux-signed-hwe-7.0 isn't listed as an affected package either.
Yeah that literally is in "does not compute" territory for me. That page literally opens with "Ubuntu priority
High [..] 9.8 · Critical [..] Publication date 15 October 2026 [..] Last updated 30 October 2026" which is exactly why "WTF Ubuntu" is the right response here.
Canonical still maintains it. If you're just hosting some HTML or even PHP, you have a comfortable amount of time before you need to upgrade, assuming you're a paying customer.
I jest, but we had (HAD) an Ubuntu 18.04 LTS that received the backported patch for PHP2Shell, even if the version wasn't supported officially by PHP.
This is why I insist our developers use the Ubuntu repositories instead the official PHP ones: besides possible instability, PHP doesn't do ancient backports.
This is the straw that broke the camel's back. I am moving back to Debian stable now. Having NVIDIA drivers and Wlan drivers back in 2014 was great, but this is not acceptable.
I think it's just brand, ubuntu was what I knew from using it as a personal desktop and then it's the default/most obvious option for a lot of providers, I think even 10+ years ago AWS EC2 defaulted to it above Debian, digital ocean too I think?
I don't remember why exactly but it was definitely just 'linux VPS = Ubuntu' for a long time. I think they got reputation as being the 'just works' option because they were happier to include some non-free graphics drivers etc where Debian was the more pure option but most end users didn't care
But since they added snap and I started running into issues with trying to install Docker etc a few years ago I default to Debian now and most of the time I don't even know which it is.
> Stable Debian is using Linux 6.12, if your laptop has modern hardware what do you do? Can't use wifi?
And Ubuntu 24.04 LTS is using 6.8.
Ubuntu releases a new version every six months, but an LTS — which is probably what most people run in production — only every two years. Debian releases come out every two years.
So if you only run Ubuntu LTS, the release cadence is the same as Debian.
> I think you're forgetting about Ubuntu 26.04 (LTS) that is using kernel 7.0.
Which only came out a few months ago, and which only recently released its .1, so the do-release-upgrade message only recently appeared for most people.
I'd be interested to know how many folks have changed their current production over to 26TLS in the last six months. I'm guessing not a lot.
So yes, there is a newer LTS, but what is its current market share as compared to 24 TLS (or even 22LTS)?
Ubuntu releases its LTSes in even years, and Debian does its releases in odd years:
That, or just pick the kernel package from unstable or testing. Apt is smart enough that mixing packages from different versions of Debian works just fine.
(I mean nothing is 100% but I've been mixing packages for like 2 decades now and literally can't remember any specific trouble resulting from it.)
It's not apt not being smart that can cause troubles when mixing packages from various suites. There's no reason to mix in cases where you can just use backports instead.
Debian testing is way more stable than Ubuntu stable. In Debian's parlance, Testing means "release candidate", actually.
If you want real testing, you should run "unstable". If you're in for fun, try experimental.
Running Testing on my desktops and stable on my servers since forever. None of them broke, none of them created problems.
I don't care Stable running 6.x.x. It gets security updates in less than 24h, and is applied automatically before I wake up, and doesn't ship coreutils with 104CVEs, just because it's Rust.
Debian security team used to offer support for testing, but as the distro grew and attack surface increased, that was dropped. However, security incidents are patched in unstable as well and they float up to testing relatively quickly (for a desktop system, anyway). When things freeze, security updates directly land on testing as a fixup polish.
However, while Testing is "relatively secure", it's never "Server secure". I'd never use testing or testing packages in stable or any server for that matter.
The comment you're replying to makes clear that they're not using it on servers. I do the same thing (testing on my laptop(s), stable on my servers); you just have to commit to keeping track of what's going on and manually patch if you think that it's necessary.
I have to add that for me, testing definitely breaks stuff sometimes. Nothing beyond my ability to fix, though. Nothing beyond anyone's ability now that AI is around.
It's not 'as supported', sure, but I'll also note that wifi, at least, has worked on pretty much every modern laptop which I have installed Debian upon.
Back in 2005-2008 or so, I think Ubuntu was a genuine breakthrough as a polished desktop version of Linux that set a standard that various other distros, eventually, caught up to. I think Cinnamon and other distros eventually caught up on polish.
They also had credible commitments to long term support that brought people on board. I think that was enough to get them on the map, but personally as a desktop user, I haven't used it in a while, mostly sticking to Debian and Arch.
Yeah this was the same for me. When I first made the switch to Linux for my dev machine Ubuntu was the distro I was by far the most familiar with so that was just the default choice. Later on after learning more and seeing how Ubuntu progressed I regretted not going straight to Debian.
I think you are right about the branding / reputation. Personally I heard negative things about Canonical and I heard that they just basically follow Debian, so why not use the original? It's been a great experience so far. Perhaps because Debian moved to include proprietary drivers out of the box now it is extremely easy to set up.
Here in NL as well. I attribute it to population ageing (babyboom generation), but AFAIK that issue is much less severe in USA than other countries which suffered in WWII. China is going to have the issue severe due to the one child policy. That population is going to get reduced a lot (not taking into account migration).
In my EU country, making an appointment got extra steps asking about one's mental state, namely depression or loneliness. One wonders if this age of social atomization, people (probably mostly those elderly) are making unnecessary appointments just to have someone to talk to.
That may be part of it but my guess is that since patients tend not to proactively mention depression and loneliness to their doctor, the doctor's office wants to know in advance whether they should be referring you to a mental health specialist.
Local minecraft server definitely requires port forwarding at the router... as I've learned to my chagrin that Starlink doesn't support port forwarding... Goodbye self hosted minecraft. Did it for nearly a decade and cannot anymore.
Honestly didn't even know if it was something [genericized, or specific?] like "fedora" or "ZFS" (where there are multiple wrappers of it) so thanks for all the help from everyone.
seriously: I am a bluecollar electrician that has absolutely no clue what I am doing. I have several machines because I constantly >BRICK< OSes...
As I only really learn visually (i.e. I love GUI environments), LLMs have enabled me to (quite dangerously, I might re-enforce) finally explore Linux (from MacOS for ~40 years).
I have tried for a long time (to adopt any Linux) – the fact that an LLM also won't be a sassyb when asking simple questions... is one reason I am so comfortable with my/our future(s).
> What is Ubuntu offering that Debian doesn't provide?
Surprised how many answers here are on "social" reasons, and ignoring that Ubuntu does provide genuine additions to Debian.
Ubuntu includes additional proprietary drivers to Debian. So there are legitimate hardware cases were Ubuntu will work out the box and Debian won't. I can't speak for how many people need those drivers, and how much of choice is down to defaults/inertia etc.
From hearing interviews with PopOS folk, I think this is also a big reason people choose Ubuntu as a base for a lot of Distros instead of Debian.
Using Ubuntu as a base became popular partly for the hardware support, codecs, ease of installation. Typing this from Linux Mint, which offers both the default Ubuntu based edition, and LMDE (the Debian Edition).
Debian has caught up, but it's been a minute since I've installed it.
to capture the cloud market, you also have to capture the mindshare at the desktop market. Do you think a new Linux distro comes out and people just install it on their servers? They try it out on the desktop first to see if they like it. It's why Fedora exists to get people into RHEL.
> Precisely, I really don't follow this discussion. Cutting edge drivers is what I want on my gaming PC.
I get the sense that the OP of this particular thread was asking about Ubuntu in general, not just the server. If it was the server, I'd understand it, but Ubuntu on the desktop still makes sense. And yes, Ubuntu is in my gaming laptop.
It had issues all the time, and finding solutions required searching online, manually. Time consuming, difficult process. Very un-beginner-friendly.
From the throve of all possible distros, one stood out. Ubuntu. Very popular. Askubuntu Forums (with coffee beans denoting ranks) was the place when, 9/10 times, the answer to your problem could be found.
So when your fedora friend cried trying to get his camera and sound working, you either found the solutions already, or asked for them and got them. Usually the former.
That was the biggest advantage of Ubuntu. Big community and wealth of troubleshooting knowledge already available. And it had the opinion of a beginner friendly system. Which made the community grow and created a large market/userbase for help threads/tutorials.
Add to that, that people are creatures of habit and 'voila - you have a lot of people sticking to Ubuntu just because they never got so pissed at them that they would change their distro.
I think it's improved, but I installed Debian on a laptop recently and the fresh system came up without wifi, which was bewildering because it connected to wifi during the install process. Took me a bunch of troubleshooting to find a rfkill setting buried in the system.
AI: you probably turned on airplane mode
me: I definitely didn't
So I love debian but it's still rough around the edges and I'm not sure I'd recommend non-technical people dive in.
This has been my exact Debian experience since I tried it on Debian 3.1. On every system at least one of network, sound, display, or power management just wouldn't work out of the box even if they did in the installer.
I ended up on Mint because I consistently found that Debian was willing to compromise their philosophy for the live distro installer, but they would never warn you that you were about to reboot into an air gapped system.
The old installer (boot-floppies) was legendarily prickly at the time Ubuntu was introduced, but it's long since been replaced by the much friendlier debian-installer. And the default install images now include non-free firmware by default, so modern wifi, bluetooth, and graphics hardware are fully supported.
To be honest, Debian now tends to be fairly vanilla and boring and it's actually Ubuntu that often ends up being a bit weirder. For example, consider how they treat the Snap packaging system for consumer software, or the rust rewrite of coreutils. Debian provides both as supported options (of course it does, Debian supports pretty much everything!), but Ubuntu pushes them to all users by default.
The traditional answer is that Debian is a bit slower-moving in both the Linux kernel and userland, so people who want current versions of popular software often find that they have to do some extra work in Debian.
A gradually increasing number of popular userland applications have been publishing their own apt repositories however so this is less of a problem now than it used to be.
Over the years though I've found that I much prefer Debian's relative stability and more thoughtful, if slightly plodding, release cadence.
Ubuntu issues a version release every 6 months, and there are updated packages in the interim.
I'm on Kubuntu (home installs) but have been looking to move since Ubuntu went over to Snaps and started breaking everything (MX looks most likely for me). The task of moving the family over is stopping me; I've been using Kubuntu for a very long time now.
For me it's just because I've been using Ubuntu full time since 2008 and has served me well my entire career, I think it's fair to say it's the flagship desktop OS that introduced many to Linux.
I feel like we're close to a post-distro era of operating systems though. My ansible playbook customizes so much already it wouldn't take too much more to just start from debian tbh.
Me same. I'm on ubuntu since 16.04 and it's annoying switching, because I'm used to it so much. Definitely switching on Debian, because they're not shipping software through apt anymore (eg. browsers). I'm running that through nix right now, and I don't want to deal with this nonsense.
I was thinking of just going entirely to Nix. The last time I tried it was 2021 (on a dual boot where I also tried Arch cause my colleague was bemoaning my Ubuntu usage). Yeah, it is annoying having to look up how to configure things the Nix way, but it all makes sense and it stems from the fact every application does it 'their way'.
Either way, I just wanted to note you can use APT to include Mozilla's Firefox and Thunderbird repo. That way, you get a .deb from them.
One specific thing I like about Ubuntu: I know a new version gets released every six months (I believe OpenBSD innovated this?) and the version is recognized by date. The LTS is released every two years around april in the even years. Otherwise it is april/october.
> it's annoying switching, because I'm used to it so much
Since you're switching to Debian, could you tell me what you don't understand in Debian that was working fine on Ubuntu for you?
I am not an Ubuntu user, so it's hard for me to know. But I find it very surprising that after 10 years on Ubuntu, it would be "annoying" to switch to Debian.
Install Ubuntu and you get 10-15 years of support of your current software stack.
Install Debian and you get 3-5 years of support.
Ubuntu also invests a lot into their desktop experience while Debian is closer to stock Gnome. That's more of a preference thing, though.
Debian has also traditionally been a pain to use with proprietary software. Nvidia drivers, WiFi firmware, you name it. It got better in the past years but it's hard to shake the bad name.
I only run Debian personally, but my dayjob company runs on SQL Server, and the officially supported options there are Windows Server, Ubuntu, or RHEL. It's not worth the effort dealing with management/auditors/etc. to try to run our prod DB on a non-supported platform.
For me, it's not so much "what does Ubuntu have that Debian doesn't" and more that "just use Ubuntu" has only bitten me twice.
It's 2009 or so and I want to try Linux. "Just try Ubuntu" they say, and I have a good time. I see that many "How to use X on Linux" guides, or FOSS software, often build for only Debian, and sometimes only Ubuntu. This is fine until snaps give me huge problems in 2018, and so I completely stop using Ubuntu desktop.
Now in 2026, I manage three servers (two on Ubuntu), one Raspberry Pi (on Ubuntu), and two Linux desktop installations. I stopped using Ubuntu desktop in 2018 but snaps are less problematic for my server workflows, so now I have three Ubuntu server installs. On my desktops and my one non-Ubuntu server, I find myself sometimes missing Ubuntuland. (These aren't Debian though, so I might just be missing Debianland.)
"Just use Ubuntu" is now something that has bitten me in using servers. Two bites in 17 years is a fantastic track record. But this slow response to a CVE fix has me looking at Debian, and this has shaken my faith in canonical. "Do they pull in upstream security fixes quickly" is one of my first questions for any FOSS I use.
But my servers aren't Nix or IaC or whatever, and so... Taking them down and putting them up would take a lot of time and risk, which are two things I'm not so willing to spend. Maybe it's 10 minutes, or maybe there's a bandaid fix I have from 2023 that I forgot about and would need an hour to re-derive. So, I find myself taking the security gamble instead.
Ubuntu offers a path from free use to paid first party support. For me, that makes it very attractive for a startup or small business that may want to add a support contract later. Ubuntu makes it a lot easier than Red Hat. Paid support for Debian is via third parties. Ubuntu is a solid distro, although I think Debian is a better one if paid support isn't an important feature to have.
Ubuntu has a timeline for how long they will provide updates for a given long term distribution release. I moved over to Ubuntu back when CentOS was converted in to a Fedora type release without a long term commitment to providing security fixes.
This is the big reason that I see a lot of companies using it over Debian.
Five years of guaranteed updates, with an option to pay for another five years ticks the box for accreditors and the like.
The much vaguer Debian policy that a release will be supported for some undetermined period based on how frequently they release, and then get some kind of volunteer-based LTS support for a couple of years after that, and then maybe further through some third-party ELTS program is a much harder sell.
This. I can't believe not a single comments above this one addressed the previsibility Ubuntu offers over Debian. It was even one of its founding reason[0]:
We migrated to Ubuntu from CentOS as well. It was simply because Rocky wasn’t established enough at the time and we haven’t had a reason yet to again look elsewhere. Tho we haven’t also phased out most VMs for containers of some sort.
For some reason I had feeling that Ubuntu more "serious" than Debian. I mean they're asking for money from people. So it's basically Debian with paid services. Can't be worse than Debian and probably is better, maybe they paid some engineer with these money to patch things faster.
That's just some rough reasoning in my head.
Also when you install third-party software, 100% of them will support Ubuntu. That's more about workstation usage, though. But having tested platform matters.
Historically, Debian didn't ship proprietary wireless firmware in the installer (because it was proprietary software, and Debian doesn't do proprietary), so you couldn't install it on most laptops without plugging them into wired Ethernet to download the wireless firmware packages from non-free.
They changed that a few years ago, but plausibly the underlying prioritization of end-user experience is still lower than Ubuntu's degree of user focus.
I still wish Mark would rename his company "Ubuntu". He's a great guy, the company does great work, but I keep getting undeserved credit for it because we wouldn't sell him the domain name.
If your infrastructure doesn't use landscape, kernel hot patching, JuJu or similar Canonical technology, or doesn't have its own Snap storefront, there's no need to install Ubuntu. Rest is just momentum.
Debian used to move a bit slow in terms of userspace, and that's true, but for servers, that's a non-issue for the last 20 years or so (from my experience).
On the Desktop side, Fedora and Ubuntu moves faster on the userspace front, but if your system is behind a NAT, and you know what you're doing, Debian Testing is just as good, more stable and it's rolling (except when it's feature freeze, but a stable workhorse is better than a shiny but breaking one).
Debian allows me to sleep well at night, provides guaranteed updates, and works rock solid all-round, so I won't be touching Ubuntu for the foreseeable future. Esp, with controversial choices like uutils, etc.
MySQL. You can make a totally valid argument that sites should just switch to Maria DB instead, but there's also no doubt that dropping MySQL support from Debian cost it a lot of LAMP servers. That, combined with Debian's release cadence which made it difficult to run numerous PHP apps basically pushed LAMP servers to Ubuntu.
Proprietary drivers, desktop first experience similar to how Mandrake used to be, or SuSE, and the most relevant, in regards to proprietary software on Linux distributions, it tends to be either Ubuntu or Red-Hat.
Familiarity. Many Ubuntu people(who were introduced to Linux via Ubuntu) never change horses. I am speaking about IT people not common folks.
You and I know Debian isn't much different, they don't know cuz some never investigated. I say some because they landed in a role with a company that is Ubuntu and never had reason to learn anything else.
Debian by default has had ancient versions of stuff, and if you want third party software, Ubuntu has more mindshare so it was more likely to be tested - anything from graphics card drivers to Steam games.
When a non-technical person asks me “which Linux?” I recommend Ubuntu because it is about as gentle an experience as Linux is going to be. The install is friendly and the culture is less RTFM than anything else.
Those are the same reasons I run Ubuntu on my laptops that aren’t running Windows…I prefer low friction to arguable technical superiority. I’ve looked at other distros in the past and decided they weren’t worth the bother…To Me.
But that’s me, not you or anyone else. And my use case not yours or someone else’s.
At my company, it’s the pateena of “enterprise”. I came to th company with strong open source bias. The more traditional/conservative IT guys were all about Microsoft and RedHat. When I lobbied hard for some Debian assets, Canonical was the compromise. But I think we’re real close now to seeing the next round of allocations be straight Debian.
I'm not a Linux user, but occasionally self-host some stuff.
One time I tried Debian instead of Ubuntu, it was a lot of "this is not installed" & "this is not set up" errors during setup process of software I wanted. In the end I succeeded in doing what I wanted, but I also wasted time on doing things I never have to do when using Ubuntu.
But we're talking about running a server in production here.
If one can't be bothered to install what is needed, maybe one should not run a server in production?
Quickly running something on your LAN for testing is different, but if you expose it to the Internet, probably your main concern shouldn't be "this is not installed".
Ubuntu did what Debian failed at. Better LTS, More features including drivers, available by default by most providers, lot more branding/documentation and in the early days, easier distribution. I am old enough to remember distro like SuSe Linux etc and when Ubuntu came on scene, it became the de facto.
> What is Ubuntu offering that Debian doesn't provide?
I'm on an nvidia jetson which comes out of the box with Ubuntu pre-installed (it's slightly more complicated but that's the gist). You can run other OSes but it is a messy experience and you can easily run into problems.
Yes, it is shitty from nvidia that they do it this way. But it is also convenient.
Just that it’s already installed, and I haven’t tried a new distro in over a decade.
But 15-20 years ago it was easier to install the nonfree stuff on ubuntu, like drivers and DVD playback and stuff. I don’t know if its still like that.
I never understood ubuntu as a server over debian, but for a desktop it was a nicer experience for a while.
They test run a little more tests on their backports (and have the manpower to actually look into what is failing) and they have really far out EoL once the kernel release is selected at fixed intervals. So if you managed to get the capabilities that you care about in their tests, there is a low probability that applying updates will cause some catastrophic outage or data loss over the next 10 years. Which can be improved further by fine-tuning phased update rollouts.
Unfortunately, they did in recent history manage to still break iptables, zfs, nilfs and a bunch of machines with weird (arguably broken) firmware anyway, so my personal comparison between Debian (or simply directly the Kroah-Hartman/Levin stable upstream) and the Ubuntu backports is not exactly in favor of Ubuntu.
They probably don't know Mint was based on Kubuntu. Or that they all - like DSL, Knoppix and others are all based on Debian and if you're brave, you can pivot to Sid from each of them.
When I worked at Canonical, the funnel I observed was Gamer Culture and the Chronically Online. They don't know from Debian.
Approx. two years ago I saw a teacher at my IT school trying to install Debian on a students virtual machine, side by side to a Windows 11. Just for fun, while watching them, I installed Ubuntu side by side on my virtual machine. These two were not done after three sessions and ultimately failed to install Debian. The installation GUI was full of cryptic words I never heard of and looked like from the year 2000. Meanwhile, the Ubuntu installation went flawless. it was done in under 15 minutes, the GUI looked modern and sexy. All I had to do was enter a nick and password, and drag a slider to tell the procedure how much space I want to reserve for Ubuntu.
FIPS mode? It's a pretty niche requirement, but I was under the impression that options are somewhat limited for FIPS-compliant crypto (both disk and networking)?
Consumer-centric customizations and non-free package options.
It’s somewhat akin to answering “How can I add stuff like OneDrive to Linux and not have to configure/self-host everything?”
I used to like Ubuntu and Canonical products and these days I’m more indifferent towards them. Their products have a place, but I wish Canonical would stop killing off some of the more interesting side projects.
I used Debian on my machines (after I got past their ideological view on drivers and found I could get them separately and made it work) ... until a patch came out and WiFi was broken on my machines. I went back to Ubuntu, have not had issues like that. Ubuntu works reliably, from my experience, on real world machines.
Enterprise support contracts for Linux and the compliance legal liability. No large commercial companies would run purely contributor supported systems because of the lack of those two things.
For desktop use, new-ish user-facing packages without any hoops (such as backports) jumped. Especially where collaboration is involved it can be a major issue when a program lags behind its commercial OS counterparts by several months or years in terms of features and behavior.
I don’t use Ubuntu but use Fedora (and its derivatives) partially for that reason.
For me, habit. A habit I'm getting tempted to break by exactly the grumble in this post. This has been an awful ~two weeks for maintaining infrastructure and the ubuntu lag on this specific issue is contributing to the awfulness.
Desktop Ubuntu purely because of the drivers. Normally used Debian for my own servers, but haven't done that in so long, and Ubuntu is often default on cloud providers so yeah.
It's the default that a bunch of vendors package. For example, Nvidia's official CUDA images used to only be provided for Ubuntu (they have since expanded their offerings somewhat)
Suppose you are an enterprise paying large amount of money to NVidia to buy their AI hardware to run AI workloads locally. Are you going to say we will refuse the default OS (https://docs.nvidia.com/dgx/dgx-os-7-user-guide/introduction...) on such hardware and lose hardware support, or are you going to stick with the supported OS for your hardware?
Enterprises care far more about vendor support than the typical Linux hacker at home.
AFAIK Ubuntu still ships newer versions. Maybe this is just because it ships new distro versions more frequently, but the end result would still be having newer packages on the latest Ubuntu release vs the latest Debian stable. I'm not an user of either distros though, so I'll wait for someone that actually uses them to confirm/rebut.
How is the gaming experience on Debian? I'm genuinely asking, not a snark.
I use desktop Ubuntu because it's up to date and it just works for me, and I can play the latest games in it with Steam + Proton. I don't have to tweak it or do any additional downloading of stuff besides the Nvidia drivers (I actually don't remember how I installed them).
Can I do this with Debian, in a no fuss way? (I know this can be done in any distro, that's why I'm stressing "no fuss").
Not bad. Steam/Proton keep themselves updated. If you rely on Wine from the repos, you might be in for a bad time, but Heroic/Lutris/Bottles in Flatpak stay updated. You mentioned Nvidia, but amdgpu has a repo that should keep things reasonably up-to-date: https://instinct.docs.amd.com/projects/amdgpu-docs/en/latest...
For some games like WoW I use Faugus on Ubuntu. It ensures I always run the latest and greatest Proton-Wayland.
But this is the thing I appreciate about Ubuntu. I know my LTS is from 26.04. I know all my software (with specific exceptions) is backported from that. The previous LTS were 24.04, 22.04, etc. With Debian, I won't know these out of my head. Partly cause I am into Ubuntu, but also because it isn't opaque. I mean, I don't remember from which time Potato and Woody were (but I used to run both back in the days). With Ubuntu, I remember (the codenames of Ubuntu I forgot).
Rest of games, Steam handles. I'm hooked on their ecosystem, kind if for a similar reason as Ubuntu (loyally sticked to them). As European I'd prefer a European gaming distribution platform, but Steam is just good and a fair netizen. Linux-friendly, too. I own a Steam Deck, too. Only reason I'd want non-Steam is all these free games I got on GOG/Epic/Amazon, and maybe some good ol' emulation.
Nvidia proprietary drivers are generally pretty old. I did some messing around with the CUDA packages to get recent desktop drivers in order to run some games.
Right? Can I install Debian and have Steam work as well as Ubuntu? Can I install Debian over my Ubuntu (without pain) and keep my dual boot with Windows 10 situation? If yes to both, will consider!
In my experience, Linux distros on older kernels sometimes struggle with modern hardware. Especially with newer devices, features and especially bug fixes take a while to make their way to the distro.
1. Faster and predictable release cadence. New releases every six months, April and October (hence x.04 and x.10). New LTS releases every April on even years (26.04, 28.04, 30.04, etc).
2. The LTS releases are supported by Canonical for at least five years on the free tier, and up to fifteen years with paid support contracts.
Agreed. Two weeks is pathetic. But, yes, I went over to Ubuntu because they were supposed to provide five years of security updated.
When I interviewed with them a couple of years ago, I got the sense there was a lot broken with their culture. It was the best choice back when RedHat/CentOS stopped providing long term security updates, but now that Rocky Linux is around, it’s getting to be time to jump ship again.
Also, almost every other time I upgrade Ubuntu, it's a shit show. I've seen the renaming of network interfaces, loss of default routes, systemd jobs that take several minutes to timeout... It's like rolling the dice. All the problems were fixable, but still an annoyance.
>What is keeping people on Ubuntu instead of just using Debian?
1. It uses much newer packages and people want shiny
2. It was marketed as one of the easiest to use linux distributions maybe 15yr ago or whatever, so a lot of new people and then tutorials went to it because newer software and features just worked.
3. What is keeping them on it now? Familiarity. Inertia.
I would need to reinstall OS on my laptop and deal with all time-consuming migration stuff for everything that changed and to configure Debian where it is doing weird things
> What is Ubuntu offering that Debian doesn't provide?
This is now trivial with agentic tooling. I recently used a separate laptop and VM over a weekend with an agent to complete a full migration. Cost is hours and a dollar in tokens.
Speaking as somebody who stayed on it way too long (until 10 years ago, maybe) it was because people constantly told me scare stories about how difficult it was to configure into something usable.
I had to go through the torturous path of Ubuntu -> Mint -> Mint Debian -> Debian. The last step was after I used a Debian live disk to do something and I could see that the stories were nonsense; just something that had adhered to the word Debian in my mind through repetition.
The two worst parts about it were 1) that I had long left Ubuntu on servers and had been using Debian there for years - I was just afraid of the desktop for some reason, and 2) that if I had just listened 15-20 years ago when people told me that FrankenDebians were nothing but problems, I would have never been caught in the net.
I've never been a fan of Ubuntu's business practices, but I'm just generally not into Debian derivatives anymore. If I were to leave Debian, it would be for an entirely different (and philosophically different) distro. I probably make an exception for Devuan, because it's only trying to change one thing (that I think of as the biggest threat to Linux, the final boss evil spawn of RedHat.) Devuan is an escape hatch for when the rugpull happens.
It's just the default target. For backend stuff, you're right that there's really very little true value. But client software just has a lot of complexity. If you run binaries from wherever, they're probably built and tested on Ubuntu first. Like, your vendors won't support distros officially, install scripts and AppImage integrations are going to tend to assume stuff. Driver/runtime integration for things like binary GPU stacks are going to document Ubuntu first. If someone makes an assumption about Python version (a personal peeve -- LOTS of python software ends up lagging the tip, it's not a super compatible ecosystem), it's going to be that you're running Ubuntu LTS version "one before latest", etc...
Are those fatal flaws? No. But lots of people just don't want to deal with it. And there's a market for that.
Because every where you used to go on the internet you read that debian is “slow” on updates but stable as a trade off, if you are after certain new packages you have to use Ubuntu, also, some use cases (say jetson boards) have ubuntu by default plus nvidia drivers.
Ubuntu is the gateway drug to Debian, in a lot of ways. You get used to GNU/Linux with Ubuntu, then you find out that there are more refined options and go for those, and a not-insignificant part of that crowd likely goes to Debian because of how familiar it is.
I agree btw. But I've been using Linux since end of 90s (I barely made use of the 2.0 Linux kernel series). I quickly established on Debian in the Potato/Woody era. Debian, back then, was severely slow with new releases. So I ended up with Testing. Which got slower security updates than Unstable. Which sometimes broke (like any rolling release does). Back then Ubuntu got released (we talking '04 and '06). And I just sticked with Ubuntu. On servers, too. I endured it all, including the Amazon spyware, the ads in MOTD, and the switch to an inferior in-house software management for some package (which name we won't mention).
I think it's a good opportunity to remind those reading this thread that they need to talk to their children about Arch Linux before someone else does.
I know it seems innocent enough at first, setting up a system just the way you want it and learning a lot of Linux's userland internals while doing so, but before you know it you're installing esoteric window managers to get your theme just right and hunting for the perfect picture of an anime waifu to be your wallpaper, all while telling others that you "use Arch, btw". Always sad to see someone fall into that sort of life.
Back when I used Ubuntu it was because I was tired of being excited about a new feature and not getting to use it until it made its way to Debian 5 years later.
If it's a corporate computer you don't want to deal with manually configuring stuff. I also want as little manual configuration on my personal machines, hence why I use Ubuntu.
It just has package for nvidia drivers. Not sure if installer will install it automatically for you (I kinda... use my install for last 12 years, just upgrading it).
For me both with AMD and NVIDIA whole hardware driver story was "install it, it works"
I'm referring to the ubuntu-drivers thing. You can do the equivalent in Debian if you add non-free repos and find the right packages, it's just more hassle. But if all you need is GPU drivers, no need for that tool.
At least Debian is on Wayland. Mint is on X11, which was causing black screen out of the box on my fairly typical PC.
Because you shouldn't have to do mitigations for this level of severity while waiting weeks for OS patch. I did that, but now I'm waiting for patch to unwind my mitigations.
You can also use the following Suricata rule if your network firewall supports it:
`drop ip any any -> any any (msg:"CVE-2026-98432: drop IPv4 packets carrying IP options (IHL > 5)"; ipv4.hdr; bsize:>20; classtype:bad-unknown; sid:1000001; rev:2;)`
All the people working at Canonical have gone through the Canonical hiring process, which is quite possibly the worst in the global industry and I can't imagine anyone competent getting through it.
You get a very different CVSS score depending on the formula you use. Ubuntu's response page lets you select between the two.
(I think CVSS is a very poor metric in cases like these; I'm just explaining what I think Ubuntu's process/position is, not making excuses for them. My read is the 9.8 is probably too high but nevertheless more accurate in this case.)
They are on my face. It's how I read a blog post and comments of people who are complaining that free software isn't being updated fast enough for them.
WTF Ubuntu! I'm not paying you for updates... so where the fuck are my updates bro?!
AlmaLinux is "boring" in the best possible way, and it works really well in WSL too. Their extended support for x86-64 v2 has also been useful on one my old computers.
I don't like ads, and I didn't like logging into SSH and seeing a nag to update to Ubuntu Pro because I had the balls to keep running 20.04 in 2023. I've seen this before on previous releases (and know how to remove the message), but seeing it again was the straw the broke the camel's back.
I have one Ubuntu Pro server and it has not received the fix yet.
Fedora would have been preferable but that is "not supported" and I had to have Ubuntu.
I think this is the important question. To everyone who is complaining while using Ubuntu for free: People whose software you use for free don't owe you anything.
Of course they don't owe them anything. Ubuntu's reputation is built primarily on people who use it (or used to) for free. They are/were Ubuntu's advocates and what made it popular.
So just as they made it popular, they can make it unpopular. People like me will simply post on our blogs and social media that they should not install Ubuntu. A typical Ubuntu user is not that high on the tech scale, and they listen to people like me for suggestions on which distro.
Calm down, man. I think Ubuntu is doing o.k. here.
What is pretty bad that people cannot read advisories anymore and fix there machines, instead crying for their mama (in this case Ubuntu).
Use this firewall rule and you are fine - it blocks the tcp options negoation - and things remain working of course:
`
nft add table ip cve_2026_98432
nft add chain ip cve_2026_98432 pre '{ type filter hook prerouting priority -300; }'
nft add rule ip cve_2026_98432 pre meta l4proto tcp ip hdrlength gt 5 counter drop
`
beyond the nft/iptables mitigations discussed codex plopped out a kernel livepatch for my ubuntu kernels in about twenty minutes. the functions are ftrace’able so no trampoline/splice shenanigans required.
I’ve always hated Ubuntu. I simply don’t understand the pitch as to why someone would use Ubuntu over just good ol fashion Debian. Better yet: FreeBSD.
To pre-empt any replies: yes, I absolutely prefer BSDs over Linux any day. But even those are flawed and I really think we missed the Symbolics golden era. THAT would be the age of "own and live in the system". OpenBSD gets closest there. At least the codebase is hackable enough.
Linux went off the fucking rails. What the fuck is that over engineered yes command?!
I moved over to Debian and haven't looked back, years ago. Why anyone would prefer Ubuntu over Debian, which is a purer, higher quality, more mature distro, is beyond me.
My opinion of the story is that it is over hyped, with my hunch being it's possibly to throw free advertising towards Anthropic, though I have no proof of that, just my personal intuition based on the handwavyness of the story.
My view is based on having used Ubuntu since 2006, Kubuntu since 2023 or so and a serious stint on Debian until they put out a patch via regular updates that bricked my machine's wifi (all of them). So my view is based on real world experience and your comment "Your view does not seem to match reality" doesn't seem to take my experience with Ubuntu and Debian into account.
Ubuntu (and Kubuntu) have never bricked all of machines after an update, Debian did, in recent years at that. So I will argue quality in favor of Ubuntu (and Kubuntu).
What would you recommend to use on servers? Would you host you apps off Arch? Or better to take Fedora or similar? I am genuinely interested in answers not distrowars
After painful Ubuntu upgrades in the past, I moved to Alma Linux and have been very happy. It takes a small adjustment to dnf instead of apt, but realistically I was over that hump in 30 to 60 minutes and this was before AI. With AI to translate and test install scripts and the like, it might be a 5 minute task depending on how much automation you already have in place. Though even an entirely un-automated setup that is just a README.md, claude wrote me an Alma Linux version of a very ubuntu specific project that gave instructions for Alma instead of Ubuntu, and it worked almost perfectly first time and AI was able to (with prompting) see the issue and quickly found a workaround. We're a small org, but at some point when we hit scale and have compliance requirements, a migration to RHEL is also largely trivial if/when the time comes.
Good question... I run ubuntu on servers because the LTS has clear 5 years of security fix.
I use arch linux for my NAS because it's fun and I don't care if it occasionally goes down but I wouldn't use it for production (on my NAS it's mostly stable but has gone down a few times)
So what's next? Centos is a rolling upgrade, nixos?
As always, it depends on how and what you're managing on it.
VPS/VM?
Debian is a great choice. Use it as base and run your software via systemd+podman if you want the most up to date stuff, Debian tends do lag a bit. It is very low maintenance.
Bare metal?
Fedora Atomic is awesome. It does require an update every other week since it keeps packages closer to upstreams, but this is where the immutable base shines, any issue is an easy reboot to revert. Also systemd+podman for your own software.
I wouldn't recommend Arch on servers.
Edit: clarified Fedora immutable spins are called Fedora Atomic.
I use Arch for servers too, for almost a decade, and to my memory only once I had an issue. That was booting off an encrypted RAID and some change which needed some investigation and then reconfiguring. I am planning to run them servers on Arch for as long as I can. It’s a bliss to never upgrade my system (only update it).
The fact that Ubuntu (still) hasn't patched this (despite the fact that I'm pretty sure Opus 5.5 could figure it out in a few minutes) is pathetic. And it's very annoying for me because I have two servers that I need to consider migrating off of it now because Ubuntu clearly doesn't care all that much about security vulnerabilities like this. Get your shit together, Canonical. We all know you can do way, way better than this.
NixOS also makes it much easier than ubuntu to install your own patches and version of the linux kernel.
For example, assuming NixOS had not yet released the fixed linux version, 6.18.56 (though it has), you could upgrade to it before NixOS did it upstream with this one line:
The debian and redhat based distros all make it so configuring what packages are installed ('apt install' / 'yum install') is a different operation from configuring the packages themselves.
On NixOS, the specification of how to build a package, what package is installed, patches, etc are all in the same language, and so it's a lot more natural to patch things as needed.
And also, LLMs are pretty good at generating working nix, so you can have an agent apply patches to your kernel package with NixOS quite easily. Agents can also do this for ubuntu or redhat, but in my experience they're much worse at it, and it's harder to undo mistakes if they mess up.
Substantially worse in my experience. They build the whole OS in CI which is slow and unreliable, and as a result it can take 2+ days for updates that other distros have out in under an hour. You can try mix packages from smash or unstable builds but for stuff like kernels that’s not simple.
If you pick a specific random package update, nixpkgs often has that update months to years before other distros.
If you pick a specific CVE, nixpkgs usually is better with the exception of embargoed ones, where Ubuntu, Fedora, etc get to prepare their patched packages ahead of time.
I have fond memories of burning Ubuntu to a CD being my first introduction to Linux. I chose to preserve those cherished memories rather than sully them through actually using Ubuntu.
I have the same general feelings, but then I recall my years as an OSS developer and being abused by people who contributed absolutely nothing to my projects. Not money, not code, not documentation, not even grammar corrections. I'm sure anyone who's been involved with reasonably popular OSS can relate.
I am not contributing to Ubuntu in any way, and that puts it into perspective.
(I still directly contribute to OSS and release OSS projects, but absolutely refuse to engage with the least bit of hostility. Any of that is an insta-block.)
Edit: Whoah the downvotes and comments. I'm not saying that Ubuntu is doing well here. I'm trying to point out that a a vast percentage of the complainers are not paying customers, and maybe if they did pay, Ubuntu would have more incentive and resources to work more quickly.
People are paying money for Ubuntu, though. I suppose if only the free versions were unpatched we could consider the ethics and merits of who is allowed to complain about what, but when the paying customers are also being left out in the cold I don't think your argument has much merit.
The TCP/IP stack has one of the most stable requirements bases of any component -- modern PCs can communicate with decades-old software and hardware, and the composition of layers design means the code can be easily tested, and is a great candidate for analysis via formal methods. And once you have a formally verified implementation, the stable requirements means you can make it safe and then leave it alone.
Pretty much every OS I can think of has had one of these vulnerabilities. Microsoft had a bad one not so long ago that affected IPv6 packets, not even at TCP level. Dedicated RTOS packages that run Mars rovers have had network-level code execution exploits.
Network routing is complex enough from a management point of view, doing it fast and safely is very hard. Formal verification sounds nice, but the network stack is more than a dumb pipe.
For bugs like this, I hope the addition of Rust to the kernel will lessen the UAF vectors, but I'm sure it'll be years before that happens. The binder folks did a safe rewrite and encountered downstream companies hooking kernel tracepoints for state determination, I can't even begin to guess what they'll do to the network stack and how that'll affect adoption.
In the current age of AI, open source means exploits can discovered directly through the code. The flip side is the patches can also be managed.
We are in that period between when software was good enough and when software is certified as secure by the writers.
The days of importing frameworks and libraries written by strangers is over. I would say the entire industry is not prepared at this moment for the unpatchable event where the only solution is to power off or disconnect.
Don't expect closed source to protect you. LLMs are very happy to analyse binaries and decompile functions you need. It's barely harder to deal with software you don't have the source for. I did both security and reveng work with LLMs and they don't slow down.
Normal Ubuntu approach. Not news.
I have personally got a bunch on 10+ year old bug tickets on Launchpad and only lately got a feedback like: "is this still relevant"?
Of course, if one hides a bug long enough it will eventually disappear or become irrelevant.
That is with the implicit assumption that the mptcp exploit of this ipv4 tcp bug is the only exploit that will be found. I don't think that assumption will hold true.
I genuinely want to understand why people use Ubuntu, and especially for servers. I’m not trolling or whatever the proper word for it. It’s not sarcasm either. I must be missing something, I guess. What is the reason? Especially if you’re not paying for it. But if you’re paying for it, I’m still curious.

(* Security fix *)
Slackware is a cool distribution. I really love that it's maintained by Patrick and I enjoy the simplicity and the stubbornness of it's opinionated decisions.
I stopped using it back in 2004 when Patrick had health problems. It seems to be a passion project and it stopped getting updates while he recovered. There is a community behind it but it may mainly be driven forward by him.
It looks like it's fairly slow to get updates, generally, as the last release was Slackware 15 in 2022. Maybe that reflects it's dictator (his word not mine) or maybe it reflects it's stability.
Yet, despite all that, Slackware got this security fix around 10 days ago.
OpenBSD got a recent GeFS (COW FS, but far lighter than BTRFS and not to mention ZFS) update, I wish 8.1 or 8.2 had it stabilized, because the issues with FFSv2 would end in the spot and maybe even steal some server machines to GNU/Linux.
or maybe, just maybe, entertain for a second that upstream (linux kernel) shipped the original patch commit on October 1st with rollout to mainline on October 9th and disclosure on October 15th.
People with affected systems have been waiting ever since for canonical to ship ... something, anything. Or maybe communicate the blockers. Crickets, though.
It gets all the more egregious if you're a paying customer for Ubuntu Pro (which thank god, our company is not).
It is absolutely taking the proberbial piss when you put it into context of their bold shiny new ambitions posted on September 23rd on their official blog (https://canonical.com/blog/accelerating-delivery-of-cve-fixe...) ... failing every single listed requirement in that announcement, now 14+ days, after initial CVE disclosure.
No need for a tin-foil hat here at all. Ubuntu has a large installbase. Part of which hosts servers. And if I had to take a wild guess that userbase is about to shrink dramatically going forward.
People panicked about the issue can either apply a quick IPTables mitigation or install the kernel Ubuntu hasn't released to production yet. It's annoying that Canonical is late, but it's not the end of the world either.
Unlike Arch or even Debian, Canonical has dozens of kernels to test and verify. The downside of supporting your software for ten years across multiple chipsets and even offering in-between kernel updates is that you need to test and maintain a shitload of kernels. Testing all of those takes time.
I hope they do a write-up about what went wrong here but all the big companies were weeks late to the party. My guess is that some of the patches were causing issues when backported, or Red Hat would've released updates much sooner as well.
I mean.. how many people are using multipath on Ubuntu? This is a big issue for datacenter systems that are using fancy networking features that Ubuntu users probably aren't.
So they do. Also they mention in the golang-announce bulletin that MPTCP might not even be required for exploitation, it's just that the PoC requires MPTCP.
The patch itself isn't related to MPTCP, but the bug is hard to exploit. AFAIK, Anthropic is the only ones who claimed exploitation using their unlimited frontier models without safety restrictions. So non-MPTCP configurations may also be vulnerable, but exploiting them could require even more resources. I've tried to trigger KASAN using Qwen 3.8 27B @ local RTX3090 - no success after 96 hours.
Debian is, in every way that I know, superior to Ubuntu.
- no snap nonsense where you can't turn off upgrades
- stays close to upstream LTS kernels
- does not carry around some ridiculous kernel patch set
- no irritating adware on login
I switched after the aforementioned patch set broke containers and destroyed my server instance a couple years ago. Apparently nobody bothered to check containers before releasing the kernel.
Everyone is just using Ubuntu for free of charge for the most part. You get what you pay for.
On another note, you can probably easily install the Debian kernel onto your machine.
"But we need signed kernels!" Well, that's a big "I told you so" from the people that were against only a handful of distros being able to create signed kernels with MS derived keys like 15 years ago.
You get what you pay for? Honestly this is so very disrespectful of the work thousands of people have and continue to put into Free Software including all Linux distros (Ubuntu too) as well as other operating systems and software. Really really disrespectful.
Having to get the client into call just so they go and click authorisation for adding some signing keys on VMs (as it was in pre-boot stage) just to add some driver wasn't fun
I suspect at this point that it’s a bunch of techno-bureaucrats at Canonical who are dogmatically sticking with their release cadence because artificial justifications. I have worked in big organizations where The Process, or The $place Way of Doing Things, has become so big that the bureaucracy takes on a life of its own and you end up having a whole team of people who just manage the process so that the people actually doing the work can maybe get something done.
I haven’t used Ubuntu for a few years now but I’m glad they’re getting this trial by fire now. This new era of software vulnerabilities is going to reduce the viability of a lot of smaller distros who more or less are entirely dependent on upstream for security and reliability. I sincerely wish the Ubuntu folks well but this is a sink or swim moment, and even if they sink it will be a net positive for Linux as a whole as weaker projects get picked off like the slowest antelope in the herd.
Sorry. I just meant, Debian's free as in beer. Ubuntu can be too but I thought there was more of a visible avenue to pay for it. And I just get annoyed with the 'you are the product' as a slogan because you get used plenty, exploitatively, even if you do pay for something. And many ethical things are in fact free
The fact Debian apparently does things properly just hammers it home
What difference does it make? Version N (TEH LATEST) is considered secure until it isn't and the same show repeats with version N+1 but we already know it's also compromised.
This doesn't work in practice. That's not really how OSS works; it's a naive interpretation. I can go into details if you'd like, but first: Have you taken this approach before? What were the results? I find it usually ends up in discussions/arguments with the owners, and it doesn't get merged. And I see the other side too; reviewing PRs is a burden, and the submitters often will fix their own problem, while introducing complexity or problems elsewhere. Also, it's generally MUCH easier for a maintainer/owner to update software than a rando who wants a bug fixed.
I fix it for myself, share it upstream, and have no fucks to give if the gatekeepers review it, reject it, merge it, or belch any purity bullshit in between.
The beauty of OSS is that you don't need permission from anyone to modify the code to your own needs.
> "The free operating system that I use is not giving me enterprise level security updates"
Canonical absolutely is marketing enterprise security updates (at least for those who pay). I don't see this in the paid ESM updates channel yet either?
> Oh and btw, distros run by volunteers (Debian, Arch, Alpine...) hve shipped the fix. Meanwhile Ubuntu, made by a company that sells security subscriptions, hasn't. This is true as of 2026-11-02 14:48 UTC.
Ubuntu is one of the larger companies in the OS space and advertises themselves as providing long term support with rapid security fixes. AFAIK they haven't released a fix for their paying customers either. If they were complaning about arch or debian then I think you would have a strong point, when those distros have fast fixes but ubuntu doesn't I'm not so sure they that criticism of ubuntu is unwarranted.
(Also, ubuntu already has the fix. What they're dragging their feet on is releasing the updated version. I don't think anyone outside ubuntu can help with that process)
Probably depends on the company. Plenty love to publish useless blog posts about how “We, a SaaS company that produces React components, fixed a vulnerability in Ubuntu Kernel” because we’re involved in all of our tech stack like that. Linux kernel, node and react is our stack and we take ownership of it seriously dawg.
The most famous not-free-as-in-beer OS that specifically marks enterprise as their target market actually only fixed this yesterday... whatever you may want to take from that.
> Why is this CVE high priority?
> See ubuntu cvss score
That's it, we don't even get a period on this TBD of a sentence. It's followed by a generic link that explains what "Ubuntu Priority" is, but that page contradicts their choice. Note that it doesn't offer any mitigations either, and even the (horrendously unclear) description is copied from the NIST page, so there's no actual message from Ubuntu.
I already had a bad feeling the first time I saw "Get more security updates through Ubuntu Pro" on `apt upgrade`, this is now the kick I needed to move to a different distro.
[0] https://ubuntu.com/security/CVE-2026-98432#priority-reason
Some of my clients may be surprised by this change, as I once advocated for Ubuntu as a good choice for a development and deployment platform. While that has not been true for quite a while, they have now jumped the shark into eel-infested waters; I cannot take them seriously any longer.
On desktop, if you need proprietary drivers, Ubuntu is easier to set up.
But yes, if debian works for you, I wouldn't use Ubuntu.
It doesn't have much to do with this CVE, but if you're trying to sell to the US government, it will often be a requirement, which means that a company making money from those sales will not easily be able to move to a distro without that certification.
presumably they mean meeting fips standards https://en.wikipedia.org/wiki/FIPS_140
>why is FIPS unique to RHEL
its not
>what has FIPS got to do with this CVE?
it doesnt. it is brought up in reply to the comment.
https://packages.debian.org/trixie/openssl-provider-fips
It's just the library, nothing special about the OS.
https://csrc.nist.gov/projects/cryptographic-module-validati...
As far as I know, compliance comes with an external module:
https://openssl-library.org/post/2025-03-11-fips-140-3/
This module seems to be in Debian:
# apt-cache search fips | grep open openssl-provider-fips - Secure Sockets Layer toolkit - cryptographic utility
# dpkg -L openssl-provider-fips /. /usr /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/ossl-modules /usr/lib/x86_64-linux-gnu/ossl-modules/fips.so /usr/share /usr/share/doc /usr/share/doc/openssl-provider-fips /usr/share/doc/openssl-provider-fips/changelog.Debian.gz /usr/share/doc/openssl-provider-fips/changelog.gz /usr/share/doc/openssl-provider-fips/copyright
There seems to be the validation process, which supposedly must run on each machine it is used on.
openssl fipsinstall -out /tmp/configfile.cnf -module /usr/lib/x86_64-linux-gnu/ossl-modules/fips.so 2>&1 | tee /tmp/result.txt
--
The above are from my notes, and a test run. But I don't see how Redhat is "special" here. If the module loads and cites compliance, you comply.
It isn't a validated build. It works the same, but it isn't sufficient if you actually need a validated FIPS module.
> It's just the library, nothing special about the OS.
If you need validation, then the kernel also need to be validated.
Now, it isn't impossible to get a FIPS validated system working with Debian, but you will probably need to contract with another commercial provider like WolfSSL to get validated components. Or compile things yourself. But that is more complicated and involved than just paying for an OS that is validated off the shelf from Ubuntu, Red Hat, or Suse.
I took the lazy Mint route with my most recent machine since I wanted to use it for light gaming with minimal fuss. I'm going to redo it with Nix sometime soon because the value prop simply isn't there and I'd like to try a declaratively-configured distro.
Christ that was 2008.18 years ago. My Linux 'experiment' is old enough to vote
[edit] omg circa 2006, firefox was still new back then
If there’s another option I’m unaware of, I’d love to hear it. Also to be fair, I didn’t evaluate Sid for this, only Stable.
They can pay for Debian support! (I’m not 100% sure who they should go to, but e.g. Freexian are doing Extended LTS for Debian [1], so I suppose they could do a regular support contract as well?)
[1]: https://wiki.debian.org/LTS/Extended
Ubuntu still has the superior installer by a good margin, but it does sometimes like to crash when run offline. Debian's installer at least has the option to go text only. There is also more work to do after the install is finished on Debian, but since that's a script it's not such a big deal.
The one bit of the Debian installer I dislike the most is how if you aren't online when you do the install you get a completely empty sources.list, and the Debian sources are a lot more complicated than Ubuntu's. Debian's support for third party drivers like nVidia graphics is also more complicated and confusing than Ubuntu's.
[1] https://docs.oracle.com/en-us/iaas/Content/Compute/Reference...
Anyway you are right, I would have switched already if Debian was available. I guess AlmaLinux could be an option to consider, since I've read in another comment that they've patched ahead of upstream for several vulnerabilities this year.
(But 100% agree this shouldn't be necessary).
And this is how Ubuntu describes the vulnerability to sysadmins:
How is this in any way, shape, or form acceptable two weeks after the CVE was published?It's so much worse than this, and there is a staggering amount of misinformation running rampant about this bug.
MPTCP is not a requirement, it can be exploited merely by sending specially crafted TCP packets with (any) IP options set. No special MPTCP support, web servers or any specific software listeners are even necessary at all to trigger it, just send the packets and boom.
I think the reason people assume MPTCP is a requirement is because that's what the PoC used... but MPTCP itself also doesn't even rely solely on IP options.
Ubuntu also does not even list a single mitigation strategy... at least RHEL did.
And like I said, any normal TCP packet that contains IP (not TCP) options can trigger the bug. I cannot emphasize enough how important and absolutely ridiculous this is.
Like the post says, this is big enough to get a massive amount of people to completely stop trusting Ubuntu entirely and jump ship.
I assume this is unrelated to the Ubuntu situation, but how does a grammar checker go down? We've been doing offline grammar checking since computers had 64K of RAM.

Agreed! I know this is a bad month, but this is poor form from several vendors that tout "we'll handle XYZ aspect of security for you".
* https://launchpad.net/ubuntu/+source/linux
You can pull them down with a "-t" added to your apt-get (but will not appear by default).
26LTS had the new kernel go to the updates/security repos on October 28.
How does that look like exactly?
First, if this CVE did truly put every Ubuntu machine on the Internet at risk, we'd know about mass compromises by now, and there haven't been any reports. It means the CVE is not trivially exploited.
Second, the gravity of the CVE dictates the security release cycle. Emergency kernel patches carry risks of their own, and it would be worse to hurry a non-critical patch and crash a part of their massive user base.
Edit: I've been enjoying this comment going up and then into the negatives, what a roller coaster.
The post gives no details about what this vulnerability is, how critical it is, how it is impacting them personally, how vulnerable their servers are, how they are working around it.
Just a title designed to generate the maximum outrage followed by a few meaningless lines.
Yes it does? And Ubuntu is selling security subscriptions and doing a poor job of it, These aren't open source volunteers, this is a paid product.
They have also not shared why they didn’t patch their kernel directly when updated versions have been available for a couple weeks now. Why wait for Ubuntu at all?
From the article the bits you need to know:
1. CVE-2026-98432 is a critical (CVSS 9.8) bug.
2. Anthropic says it built a working exploit that gets root on a server.
Also, the author uses Claude to make 270 LoC bash scripts. I think his opinion doesn't matter.
He doesn't. So, maybe he is a Karen and you are being a little protective of someone who is whining like a child.
The post gives enough detail, there is a vulnerability that allows root access on servers on the TCP stack, so literally accessible if you are running any service. There are exploits in the wild. Debian has the patched kernel, Ubuntu does not 2 weeks after the CVE is known.
> how critical it is,
9.8 out of 10 btw.
> how it is impacting them personally,
They are clearly rather upset by the lack of an appropriate response.
> how vulnerable their servers are,
They are literally open to anyone with an AI subscription.
> how they are working around it.
They are migrating off Ubuntu.
They have kernels out you can install if you really need them, they're just not merged into production repos yet.
This. You are welcome to publish patches and demonstrate how people can fix their own machines out of band with what Ubuntu does. This costs you... 10 minutes with AI help?
While it's easier than ever to complain this year, I'm patching all the things while on a walk or not at my computer, it's great!
Welcome to the world of tomorrow
what? the literal first paragraph says:
"In case you missed it: CVE-2026-98432 is a critical (CVSS 9.8) bug in the Linux kernel's TCP code. It's been there since 2016, so virtually every Linux server on the planet has it, and it can be hit remotely"
It's not optional.
Maybe it's time for StealMyBitcoinV2…
https://ubuntu.com/security
server: nginx/1.14.0 (Ubuntu)
thanks for that :)
Also this vulnerability is not strictly about mptcp, although the exploitability is not clear.
We keep doing this to ourselves. Heads should roll at Ubuntu. Start that process right now? You can't. You see, nobody is directly available to sue. It does seem that nobody ever truly cared about that. The insecure codebase and tech debt shall continue to grow because that is the gift.

Much like with PHP2Shell, it doesn't need to be utterly trivially exploitable to be a big concern.
https://ubuntu.com/security/CVE-2026-98432
It’s still, over a week after disclosure and patches, unpatched in Ubuntu.
As for me, a part of me wants to move over to Rocky Linux 10.
For example, I have linux-image-generic installed, description "Generic Linux kernel image This package will always depend on the latest generic kernel image available." and then "Depends: linux-image-6.8.0-147-generic, linux-modules-extra-6.8.0-147-generic, linux-firmware, intel-microcode, amd64-microcode"
Why isn't there linux-image or linux-modules-* listed as an affected package?
First I thought it was the source package / binary package distinction, but e.g. linux-image-7.0.0-38-generic says "Source: linux-signed-hwe-7.0", and linux-signed-hwe-7.0 isn't listed as an affected package either.
So what's going on here?
Does Rocky use their own community-built packages, or does it use RHEL's?
Because I don't think Red Hat have released patches yet either?
https://access.redhat.com/security/cve/cve-2026-98432
For RedHat/Rocky 10:

This is why I insist our developers use the Ubuntu repositories instead the official PHP ones: besides possible instability, PHP doesn't do ancient backports.

From the linked Ubuntu CVE page
" Vulnerable system - Confidentiality impact Low
Vulnerable system - Integrity impact Low
Vulnerable system - Availability impact High
" suggesting it's more of a denial of service. So which is it, there are dozens of kernel CVEs fixed in the linked debian email.
I don't remember why exactly but it was definitely just 'linux VPS = Ubuntu' for a long time. I think they got reputation as being the 'just works' option because they were happier to include some non-free graphics drivers etc where Debian was the more pure option but most end users didn't care
But since they added snap and I started running into issues with trying to install Docker etc a few years ago I default to Debian now and most of the time I don't even know which it is.
And don't get me started with Debian testing. I want a LTS distro not a testing one.
And Ubuntu 24.04 LTS is using 6.8.
Ubuntu releases a new version every six months, but an LTS — which is probably what most people run in production — only every two years. Debian releases come out every two years.
So if you only run Ubuntu LTS, the release cadence is the same as Debian.
Which only came out a few months ago, and which only recently released its .1, so the do-release-upgrade message only recently appeared for most people.
I'd be interested to know how many folks have changed their current production over to 26TLS in the last six months. I'm guessing not a lot.
So yes, there is a newer LTS, but what is its current market share as compared to 24 TLS (or even 22LTS)?
Ubuntu releases its LTSes in even years, and Debian does its releases in odd years:
* https://en.wikipedia.org/wiki/Debian_release_version_history...
(I mean nothing is 100% but I've been mixing packages for like 2 decades now and literally can't remember any specific trouble resulting from it.)
You either want to have the new stuff or LTS. You can't have both.
If you want real testing, you should run "unstable". If you're in for fun, try experimental.
Running Testing on my desktops and stable on my servers since forever. None of them broke, none of them created problems.
I don't care Stable running 6.x.x. It gets security updates in less than 24h, and is applied automatically before I wake up, and doesn't ship coreutils with 104CVEs, just because it's Rust.
Again. Stable is for servers, testing is for personal use.
I never argued otherwise, ever.
However, while Testing is "relatively secure", it's never "Server secure". I'd never use testing or testing packages in stable or any server for that matter.
I have to add that for me, testing definitely breaks stuff sometimes. Nothing beyond my ability to fix, though. Nothing beyond anyone's ability now that AI is around.
That's interesting, can you give an example? Asking as a curious Debian user.
It's not 'as supported', sure, but I'll also note that wifi, at least, has worked on pretty much every modern laptop which I have installed Debian upon.
Why not just install a newer Linux version from the official backports repository if you need it?
https://backports.debian.org/
But nobody runs Debian stable on their laptop.
They run Debian unstable or testing, with firmware.
And everything just works
They also had credible commitments to long term support that brought people on board. I think that was enough to get them on the map, but personally as a desktop user, I haven't used it in a while, mostly sticking to Debian and Arch.
Ubuntu found me (finally, with the tutorialhelp of a localLLM) in 2026, and I don't trust most of the opt-outs.
Thanks for the link (above).
Now my friends don't have trouble calling doctors, but can't set up port forwarding (not like any games require it anymore).
After October 2026, nobody should be port-forwarding IMHO.
I am next to learn about the "tailscale options" of this new world.
Wish us all luck.
Now I have learnt something.
https://distrowatch.org/index.php?distribution=debian&releas...
I am definitely still learning.
As I only really learn visually (i.e. I love GUI environments), LLMs have enabled me to (quite dangerously, I might re-enforce) finally explore Linux (from MacOS for ~40 years).
I have tried for a long time (to adopt any Linux) – the fact that an LLM also won't be a sassyb when asking simple questions... is one reason I am so comfortable with my/our future(s).
–ProbablyNotMachines
Surprised how many answers here are on "social" reasons, and ignoring that Ubuntu does provide genuine additions to Debian.
Ubuntu includes additional proprietary drivers to Debian. So there are legitimate hardware cases were Ubuntu will work out the box and Debian won't. I can't speak for how many people need those drivers, and how much of choice is down to defaults/inertia etc.
From hearing interviews with PopOS folk, I think this is also a big reason people choose Ubuntu as a base for a lot of Distros instead of Debian.
Debian has caught up, but it's been a minute since I've installed it.
What are the numbers of people still installing servers on the real hardware and needing these proprietary drivers?
Is AI changing the game where more people want bare metal and GPUs with proprietor drivers?
A fair few years ago I did run Ubuntu on my desktop and laptop when I wanted some more similarity with my servers which ran Debian.
And similar breakdowns with Fedora/RHEL.
But Ubuntu or Fedora on a server? No thanks.
Yes, for GPU workloads or just raw container orchestration platforms. Or gaming!
> Fedora on a server? No thanks.
Fedora's pokemon evolution turns it into RHEL, with not much change.
I get the sense that the OP of this particular thread was asking about Ubuntu in general, not just the server. If it was the server, I'd understand it, but Ubuntu on the desktop still makes sense. And yes, Ubuntu is in my gaming laptop.
A lot of those are running on bespoke hardware specific to the hyperscaler.
It had issues all the time, and finding solutions required searching online, manually. Time consuming, difficult process. Very un-beginner-friendly.
From the throve of all possible distros, one stood out. Ubuntu. Very popular. Askubuntu Forums (with coffee beans denoting ranks) was the place when, 9/10 times, the answer to your problem could be found.
So when your fedora friend cried trying to get his camera and sound working, you either found the solutions already, or asked for them and got them. Usually the former.
That was the biggest advantage of Ubuntu. Big community and wealth of troubleshooting knowledge already available. And it had the opinion of a beginner friendly system. Which made the community grow and created a large market/userbase for help threads/tutorials.
Add to that, that people are creatures of habit and 'voila - you have a lot of people sticking to Ubuntu just because they never got so pissed at them that they would change their distro.
AI: you probably turned on airplane mode
me: I definitely didn't
So I love debian but it's still rough around the edges and I'm not sure I'd recommend non-technical people dive in.
I ended up on Mint because I consistently found that Debian was willing to compromise their philosophy for the live distro installer, but they would never warn you that you were about to reboot into an air gapped system.
The old installer (boot-floppies) was legendarily prickly at the time Ubuntu was introduced, but it's long since been replaced by the much friendlier debian-installer. And the default install images now include non-free firmware by default, so modern wifi, bluetooth, and graphics hardware are fully supported.
To be honest, Debian now tends to be fairly vanilla and boring and it's actually Ubuntu that often ends up being a bit weirder. For example, consider how they treat the Snap packaging system for consumer software, or the rust rewrite of coreutils. Debian provides both as supported options (of course it does, Debian supports pretty much everything!), but Ubuntu pushes them to all users by default.
A gradually increasing number of popular userland applications have been publishing their own apt repositories however so this is less of a problem now than it used to be.
Over the years though I've found that I much prefer Debian's relative stability and more thoughtful, if slightly plodding, release cadence.
I'm on Kubuntu (home installs) but have been looking to move since Ubuntu went over to Snaps and started breaking everything (MX looks most likely for me). The task of moving the family over is stopping me; I've been using Kubuntu for a very long time now.
Debian is still on Python 3.13 while u until is on 3.14
That's just ONE example out of many.
I may be biased as a Debian user, but if Ubuntu now reacts slower than Debian this may push some people to reconsider their choice.
I feel like we're close to a post-distro era of operating systems though. My ansible playbook customizes so much already it wouldn't take too much more to just start from debian tbh.
Either way, I just wanted to note you can use APT to include Mozilla's Firefox and Thunderbird repo. That way, you get a .deb from them.
One specific thing I like about Ubuntu: I know a new version gets released every six months (I believe OpenBSD innovated this?) and the version is recognized by date. The LTS is released every two years around april in the even years. Otherwise it is april/october.
Since you're switching to Debian, could you tell me what you don't understand in Debian that was working fine on Ubuntu for you?
I am not an Ubuntu user, so it's hard for me to know. But I find it very surprising that after 10 years on Ubuntu, it would be "annoying" to switch to Debian.
Install Debian and you get 3-5 years of support.
Ubuntu also invests a lot into their desktop experience while Debian is closer to stock Gnome. That's more of a preference thing, though.
Debian has also traditionally been a pain to use with proprietary software. Nvidia drivers, WiFi firmware, you name it. It got better in the past years but it's hard to shake the bad name.
It's 2009 or so and I want to try Linux. "Just try Ubuntu" they say, and I have a good time. I see that many "How to use X on Linux" guides, or FOSS software, often build for only Debian, and sometimes only Ubuntu. This is fine until snaps give me huge problems in 2018, and so I completely stop using Ubuntu desktop.
Now in 2026, I manage three servers (two on Ubuntu), one Raspberry Pi (on Ubuntu), and two Linux desktop installations. I stopped using Ubuntu desktop in 2018 but snaps are less problematic for my server workflows, so now I have three Ubuntu server installs. On my desktops and my one non-Ubuntu server, I find myself sometimes missing Ubuntuland. (These aren't Debian though, so I might just be missing Debianland.)
"Just use Ubuntu" is now something that has bitten me in using servers. Two bites in 17 years is a fantastic track record. But this slow response to a CVE fix has me looking at Debian, and this has shaken my faith in canonical. "Do they pull in upstream security fixes quickly" is one of my first questions for any FOSS I use.
But my servers aren't Nix or IaC or whatever, and so... Taking them down and putting them up would take a lot of time and risk, which are two things I'm not so willing to spend. Maybe it's 10 minutes, or maybe there's a bandaid fix I have from 2023 that I forgot about and would need an hour to re-derive. So, I find myself taking the security gamble instead.
I might be moving over to Rocky Linux 10.
Five years of guaranteed updates, with an option to pay for another five years ticks the box for accreditors and the like.
The much vaguer Debian policy that a release will be supported for some undetermined period based on how frequently they release, and then get some kind of volunteer-based LTS support for a couple of years after that, and then maybe further through some third-party ELTS program is a much harder sell.

That's just some rough reasoning in my head.
Also when you install third-party software, 100% of them will support Ubuntu. That's more about workstation usage, though. But having tested platform matters.
For example, the fonts and the font rendering in Ubuntu and its derivatives were noticeably better than on stock Debian/Arch/etc.
They changed that a few years ago, but plausibly the underlying prioritization of end-user experience is still lower than Ubuntu's degree of user focus.
I still wish Mark would rename his company "Ubuntu". He's a great guy, the company does great work, but I keep getting undeserved credit for it because we wouldn't sell him the domain name.
Debian used to move a bit slow in terms of userspace, and that's true, but for servers, that's a non-issue for the last 20 years or so (from my experience).
On the Desktop side, Fedora and Ubuntu moves faster on the userspace front, but if your system is behind a NAT, and you know what you're doing, Debian Testing is just as good, more stable and it's rolling (except when it's feature freeze, but a stable workhorse is better than a shiny but breaking one).
Debian allows me to sleep well at night, provides guaranteed updates, and works rock solid all-round, so I won't be touching Ubuntu for the foreseeable future. Esp, with controversial choices like uutils, etc.

You and I know Debian isn't much different, they don't know cuz some never investigated. I say some because they landed in a role with a company that is Ubuntu and never had reason to learn anything else.
When a non-technical person asks me “which Linux?” I recommend Ubuntu because it is about as gentle an experience as Linux is going to be. The install is friendly and the culture is less RTFM than anything else.
Those are the same reasons I run Ubuntu on my laptops that aren’t running Windows…I prefer low friction to arguable technical superiority. I’ve looked at other distros in the past and decided they weren’t worth the bother…To Me.
But that’s me, not you or anyone else. And my use case not yours or someone else’s.
To this point, adding "on ubuntu" to a search gives me better tutorials.
Disclaimer: I run on Gentoo, so I genuinely don't know.
If one can't be bothered to install what is needed, maybe one should not run a server in production?
Quickly running something on your LAN for testing is different, but if you expose it to the Internet, probably your main concern shouldn't be "this is not installed".
Large enterprise with multiple knowledgeable people on payroll have different concerns than small me.
I moved all my new server/service deployments back to Debian around 2021/2022 (bullseye era).
I'm on an nvidia jetson which comes out of the box with Ubuntu pre-installed (it's slightly more complicated but that's the gist). You can run other OSes but it is a messy experience and you can easily run into problems.
Yes, it is shitty from nvidia that they do it this way. But it is also convenient.
But 15-20 years ago it was easier to install the nonfree stuff on ubuntu, like drivers and DVD playback and stuff. I don’t know if its still like that.
I never understood ubuntu as a server over debian, but for a desktop it was a nicer experience for a while.
Unfortunately, they did in recent history manage to still break iptables, zfs, nilfs and a bunch of machines with weird (arguably broken) firmware anyway, so my personal comparison between Debian (or simply directly the Kroah-Hartman/Levin stable upstream) and the Ubuntu backports is not exactly in favor of Ubuntu.
When I worked at Canonical, the funnel I observed was Gamer Culture and the Chronically Online. They don't know from Debian.
I hope that answers your question.
I used to like Ubuntu and Canonical products and these days I’m more indifferent towards them. Their products have a place, but I wish Canonical would stop killing off some of the more interesting side projects.
I don’t use Ubuntu but use Fedora (and its derivatives) partially for that reason.
I really don’t care what I run on, as long as it’s some flavour of Linux, it works reliably, and it’s secure.
Enterprises care far more about vendor support than the typical Linux hacker at home.

I use desktop Ubuntu because it's up to date and it just works for me, and I can play the latest games in it with Steam + Proton. I don't have to tweak it or do any additional downloading of stuff besides the Nvidia drivers (I actually don't remember how I installed them).
Can I do this with Debian, in a no fuss way? (I know this can be done in any distro, that's why I'm stressing "no fuss").
But this is the thing I appreciate about Ubuntu. I know my LTS is from 26.04. I know all my software (with specific exceptions) is backported from that. The previous LTS were 24.04, 22.04, etc. With Debian, I won't know these out of my head. Partly cause I am into Ubuntu, but also because it isn't opaque. I mean, I don't remember from which time Potato and Woody were (but I used to run both back in the days). With Ubuntu, I remember (the codenames of Ubuntu I forgot).
Rest of games, Steam handles. I'm hooked on their ecosystem, kind if for a similar reason as Ubuntu (loyally sticked to them). As European I'd prefer a European gaming distribution platform, but Steam is just good and a fair netizen. Linux-friendly, too. I own a Steam Deck, too. Only reason I'd want non-Steam is all these free games I got on GOG/Epic/Amazon, and maybe some good ol' emulation.
On Arch I just installed the flatpak and didn't think about it, everything works.
2. The LTS releases are supported by Canonical for at least five years on the free tier, and up to fifteen years with paid support contracts.
It's still a pretty basic reason businesses might calculate that Ubuntu is a good fit.
When I interviewed with them a couple of years ago, I got the sense there was a lot broken with their culture. It was the best choice back when RedHat/CentOS stopped providing long term security updates, but now that Rocky Linux is around, it’s getting to be time to jump ship again.
1. It uses much newer packages and people want shiny
2. It was marketed as one of the easiest to use linux distributions maybe 15yr ago or whatever, so a lot of new people and then tutorials went to it because newer software and features just worked.
3. What is keeping them on it now? Familiarity. Inertia.
> What is Ubuntu offering that Debian doesn't provide?
I have it right now at zero additional effort
And I am not letting LLM to send contents of my private files to LLM providers.
LLM can define backup job, write scripts and configs.
AI connects to blank system, builds out config and then creates scripts to run rsync.
The way some people fear AI is not realizing that it is doing the operations.
I still consider necessary to test and understand my backup system, so it will take nonzero time.
I had to go through the torturous path of Ubuntu -> Mint -> Mint Debian -> Debian. The last step was after I used a Debian live disk to do something and I could see that the stories were nonsense; just something that had adhered to the word Debian in my mind through repetition.
The two worst parts about it were 1) that I had long left Ubuntu on servers and had been using Debian there for years - I was just afraid of the desktop for some reason, and 2) that if I had just listened 15-20 years ago when people told me that FrankenDebians were nothing but problems, I would have never been caught in the net.
I've never been a fan of Ubuntu's business practices, but I'm just generally not into Debian derivatives anymore. If I were to leave Debian, it would be for an entirely different (and philosophically different) distro. I probably make an exception for Devuan, because it's only trying to change one thing (that I think of as the biggest threat to Linux, the final boss evil spawn of RedHat.) Devuan is an escape hatch for when the rugpull happens.
1. Hardware generally just works
2. Videos that use patented formats just play without fiddling
3. Proprietary closed-source software, if they even support Linux, usually releases Ubuntu binaries before anything else
Are those fatal flaws? No. But lots of people just don't want to deal with it. And there's a market for that.
Ubuntu kernels are not the one that Debian uses. The latest stable Debian is based on a 2 years old Kernel ( 6.12 ).
I agree btw. But I've been using Linux since end of 90s (I barely made use of the 2.0 Linux kernel series). I quickly established on Debian in the Potato/Woody era. Debian, back then, was severely slow with new releases. So I ended up with Testing. Which got slower security updates than Unstable. Which sometimes broke (like any rolling release does). Back then Ubuntu got released (we talking '04 and '06). And I just sticked with Ubuntu. On servers, too. I endured it all, including the Amazon spyware, the ads in MOTD, and the switch to an inferior in-house software management for some package (which name we won't mention).
I know it seems innocent enough at first, setting up a system just the way you want it and learning a lot of Linux's userland internals while doing so, but before you know it you're installing esoteric window managers to get your theme just right and hunting for the perfect picture of an anime waifu to be your wallpaper, all while telling others that you "use Arch, btw". Always sad to see someone fall into that sort of life.
It just has package for nvidia drivers. Not sure if installer will install it automatically for you (I kinda... use my install for last 12 years, just upgrading it).
For me both with AMD and NVIDIA whole hardware driver story was "install it, it works"
At least Debian is on Wayland. Mint is on X11, which was causing black screen out of the box on my fairly typical PC.

You can also use the following Suricata rule if your network firewall supports it:

(I think CVSS is a very poor metric in cases like these; I'm just explaining what I think Ubuntu's process/position is, not making excuses for them. My read is the 9.8 is probably too high but nevertheless more accurate in this case.)
I wonder what is slower, these people pulling out a credit to pay something or ubuntu fixing their issue?
Maybe grab those first, though.
WTF Ubuntu! I'm not paying you for updates... so where the fuck are my updates bro?!
So just as they made it popular, they can make it unpopular. People like me will simply post on our blogs and social media that they should not install Ubuntu. A typical Ubuntu user is not that high on the tech scale, and they listen to people like me for suggestions on which distro.
Cut the pipeline that feeds into it.
Use this firewall rule and you are fine - it blocks the tcp options negoation - and things remain working of course: ` nft add table ip cve_2026_98432 nft add chain ip cve_2026_98432 pre '{ type filter hook prerouting priority -300; }' nft add rule ip cve_2026_98432 pre meta l4proto tcp ip hdrlength gt 5 counter drop `

AI is now capable of, and being applied to, find so many bugs recently that infrastructure providers need to up their game and respond quickly.
Hopefully this is a passing phase as bugs are quickly patched, and we'll get past it without too many incidents.
For me, I view Ubuntu as the "higher quality, more mature distro" which I value over "purity".
There is a reason I moved to Debian; it is not like I just like the sound of it better.
My view is based on having used Ubuntu since 2006, Kubuntu since 2023 or so and a serious stint on Debian until they put out a patch via regular updates that bricked my machine's wifi (all of them). So my view is based on real world experience and your comment "Your view does not seem to match reality" doesn't seem to take my experience with Ubuntu and Debian into account.
I use arch linux for my NAS because it's fun and I don't care if it occasionally goes down but I wouldn't use it for production (on my NAS it's mostly stable but has gone down a few times)
So what's next? Centos is a rolling upgrade, nixos?
VPS/VM? Debian is a great choice. Use it as base and run your software via systemd+podman if you want the most up to date stuff, Debian tends do lag a bit. It is very low maintenance.
Bare metal? Fedora Atomic is awesome. It does require an update every other week since it keeps packages closer to upstreams, but this is where the immutable base shines, any issue is an easy reboot to revert. Also systemd+podman for your own software.
I wouldn't recommend Arch on servers.
Edit: clarified Fedora immutable spins are called Fedora Atomic.

NixOS also makes it much easier than ubuntu to install your own patches and version of the linux kernel.
For example, assuming NixOS had not yet released the fixed linux version, 6.18.56 (though it has), you could upgrade to it before NixOS did it upstream with this one line:
You could add the patch yourself if you needed to with: And then you'd be updated.The debian and redhat based distros all make it so configuring what packages are installed ('apt install' / 'yum install') is a different operation from configuring the packages themselves.
On NixOS, the specification of how to build a package, what package is installed, patches, etc are all in the same language, and so it's a lot more natural to patch things as needed.
And also, LLMs are pretty good at generating working nix, so you can have an agent apply patches to your kernel package with NixOS quite easily. Agents can also do this for ubuntu or redhat, but in my experience they're much worse at it, and it's harder to undo mistakes if they mess up.
See https://repology.org/repositories/graphs
If you pick a specific random package update, nixpkgs often has that update months to years before other distros.
If you pick a specific CVE, nixpkgs usually is better with the exception of embargoed ones, where Ubuntu, Fedora, etc get to prepare their patched packages ahead of time.
As opposed to only building a part of the OS?
And you can have an ubuntu userland setup and any package necessary to run cuda in mere seconds on any linux distro thanks to toolbox and distrobox.
Listened to over a decade of people chirping about the new hotness and calling my Debian servers lame, old and busted. Well look at you now!
I am not contributing to Ubuntu in any way, and that puts it into perspective.
(I still directly contribute to OSS and release OSS projects, but absolutely refuse to engage with the least bit of hostility. Any of that is an insta-block.)
Edit: Whoah the downvotes and comments. I'm not saying that Ubuntu is doing well here. I'm trying to point out that a a vast percentage of the complainers are not paying customers, and maybe if they did pay, Ubuntu would have more incentive and resources to work more quickly.
But, imagine if the complaint vs paid ratio were more equal.
Right now, the ratio is massively skewed towards complainers vs paid. (>99.9% I'd guess)
The TCP/IP stack has one of the most stable requirements bases of any component -- modern PCs can communicate with decades-old software and hardware, and the composition of layers design means the code can be easily tested, and is a great candidate for analysis via formal methods. And once you have a formally verified implementation, the stable requirements means you can make it safe and then leave it alone.
Network routing is complex enough from a management point of view, doing it fast and safely is very hard. Formal verification sounds nice, but the network stack is more than a dumb pipe.
For bugs like this, I hope the addition of Rust to the kernel will lessen the UAF vectors, but I'm sure it'll be years before that happens. The binder folks did a safe rewrite and encountered downstream companies hooking kernel tracepoints for state determination, I can't even begin to guess what they'll do to the network stack and how that'll affect adoption.
I wish life was that easy.
We are in that period between when software was good enough and when software is certified as secure by the writers.
The days of importing frameworks and libraries written by strangers is over. I would say the entire industry is not prepared at this moment for the unpatchable event where the only solution is to power off or disconnect.
Of course, if one hides a bug long enough it will eventually disappear or become irrelevant.
Yes, indeed, WTF Ubuntu?
I am a bit surprised by the panic...
IIRC it had minimal HN discussion.
No offense but Anthropic says that every time.

And Slackware too:
From: https://ftp.osuosl.org/pub/slackware/slackware64-15.0/Change...I stopped using it back in 2004 when Patrick had health problems. It seems to be a passion project and it stopped getting updates while he recovered. There is a community behind it but it may mainly be driven forward by him.
It looks like it's fairly slow to get updates, generally, as the last release was Slackware 15 in 2022. Maybe that reflects it's dictator (his word not mine) or maybe it reflects it's stability.
Yet, despite all that, Slackware got this security fix around 10 days ago.
Creepy as hell company. Had a good free Linux distro, but it's not that good anymore. It's coasting on inertia these days.
Either this was used to pop something big, or this is a jia tan situation going down.
I thought there was a flamebait automation that was prevent this sort of velocity (unless overridden)
People with affected systems have been waiting ever since for canonical to ship ... something, anything. Or maybe communicate the blockers. Crickets, though.
It gets all the more egregious if you're a paying customer for Ubuntu Pro (which thank god, our company is not).
It is absolutely taking the proberbial piss when you put it into context of their bold shiny new ambitions posted on September 23rd on their official blog (https://canonical.com/blog/accelerating-delivery-of-cve-fixe...) ... failing every single listed requirement in that announcement, now 14+ days, after initial CVE disclosure.
No need for a tin-foil hat here at all. Ubuntu has a large installbase. Part of which hosts servers. And if I had to take a wild guess that userbase is about to shrink dramatically going forward.
Unlike Arch or even Debian, Canonical has dozens of kernels to test and verify. The downside of supporting your software for ten years across multiple chipsets and even offering in-between kernel updates is that you need to test and maintain a shitload of kernels. Testing all of those takes time.
I hope they do a write-up about what went wrong here but all the big companies were weeks late to the party. My guess is that some of the patches were causing issues when backported, or Red Hat would've released updates much sooner as well.
But it doesn't sound too hard to backport a patch from Debian to Ubuntu yourself.
So if it's a critical security concern to your company, open your laptop and get to work.
Well - Ubuntu sold out to marketing rather than engineering.
Happened to Google too. Compare Google Search to 10 or 15 years ago. Totally useless nowadays.
Not to mention however many production services teams I work with build and maintain that run on Ubuntu.
Ubuntu are dragging their feet and it’s not good enough. Nowhere near good enough.
Get it patched NOW!
And if you’re on here and you work for Ubuntu, then what the hell are you doing reading this when you should be shipping a patch?
Seriously: get on it, will you?
>no snap nonsense where you can't turn off upgrades
You can disable AND uninstall snap entirely. You can also disable automatic update of the specific snaps you have installed.
>stays close to upstream LTS kernels
Same as Ubuntu, which uses 7.3 on its latest release as of today.
>does not carry around some ridiculous kernel patch set
Custom kernel patches for hardware compatibility is a very good thing, and why Ubuntu works on a lot of machines compared to other distros.
>no irritating adware on login
There is not a single ad on login, and even after. You are an ugly liar.
There's been lots of drama on Ubuntu which OP either completely missed or ignored. Ubuntu has been getting worse for over a decade now.
On another note, you can probably easily install the Debian kernel onto your machine.
"But we need signed kernels!" Well, that's a big "I told you so" from the people that were against only a handful of distros being able to create signed kernels with MS derived keys like 15 years ago.
What an awful system
That ignores those paying for Ubuntu Pro. They are not getting what they paid for.
I haven’t used Ubuntu for a few years now but I’m glad they’re getting this trial by fire now. This new era of software vulnerabilities is going to reduce the viability of a lot of smaller distros who more or less are entirely dependent on upstream for security and reliability. I sincerely wish the Ubuntu folks well but this is a sink or swim moment, and even if they sink it will be a net positive for Linux as a whole as weaker projects get picked off like the slowest antelope in the herd.
"If you're not paying, you're the product-" hey jerks, the analogy doesn't always work
Debian has a patch out, do they not?
The fact Debian apparently does things properly just hammers it home
It was a lazy reply and I apologize
Let's be clear the security vulns will never end and if you're running anything connected to the network eventually you'll get pwned.
I believe you can contribute to Ubuntu's source code right? Why don't you fix the issue then?
The beauty of OSS is that you don't need permission from anyone to modify the code to your own needs.
Canonical absolutely is marketing enterprise security updates (at least for those who pay). I don't see this in the paid ESM updates channel yet either?
> Oh and btw, distros run by volunteers (Debian, Arch, Alpine...) hve shipped the fix. Meanwhile Ubuntu, made by a company that sells security subscriptions, hasn't. This is true as of 2026-11-02 14:48 UTC.
(Also, ubuntu already has the fix. What they're dragging their feet on is releasing the updated version. I don't think anyone outside ubuntu can help with that process)
Let's see you do it.
If they don’t have the resources to handle this, they should be recruiting more help from their community
