The future of AI in Ubuntu

Jon Seager outlines how “AI will play a part in both Canonical and Ubuntu’s future”. This outline also tells us that AI will show itself in two forms: firstly in “enhancing existing OS functionality with AI models”, and secondly as “AI native” features for those wanting them. This is an extensive post, with numerous links provided, but we’re assured that “Ubuntu is not becoming an AI product” but will in fact be stronger with “thoughtful AI integration”.

Linux cryptographic code flaw offers fast route to root

Thomas Claburn tells us that major Linux distributions have shipped patches addressing a local privilege escalation (LPE) vulnerability dubbed ‘Copy Fail’ (CVE-2026-31431). We’re told what the issue is, how it can used by attackers, that its been rated as High Severity (7.8 out of 10) and much more.

Canonical, the company that makes Ubuntu Linux, says its web infrastructure is under a ‘sustained, cross-border attack’

Jacob Fox writes about Canonical’s infrastructure under a “sustained cross-border attack”, which maybe impacting Ubuntu users using some Ubuntu sites and services. Jacob notes that this occurred a day after Copy Fail’s disclosure which may concern some users, but little currently is known, and it may be simply a DDoS or Denial of Service attack. We’re also told a hacktivist group has claimed responsibility for the DDoS.

Editorial Note: This is still an active situation, and details are thus not fully known.

Covered in this include amd64v3, risc-v, arm64, pi booting, and much more. This is an extensive post as a lot of the toolchains in Ubuntu are managed within Ubuntu Foundations.

Supply-chain accountability – coming to a Rust package near you!

Petrichor Park, from the Rust Toolchains squad, announces an experimental opt-in support for cargo-auditable metadata on most Rust packages on Launchpad. We’re given details of this including why its beneficial to us, the what, how, and when, before Petrichor moves to thanking various teams and Shnatsel of Debian.

Announcing Mentoring Mondays

Otto Kekäläinen announces Mentoring Mondays which is a “recurring video call that lasts roughly 45 minutes”. Covered will be a walk-through demo of Debian packaging (what and why), a discussion on pros and cons aimed at developing judgement, and a Q&A on open source contributions. We’re told who will benefit from this, and given other details.

How Charm Tech combats Hyrum’s Law

Tony Meyer starts by telling us the Charm Tech team focuses on “considered design and stability”. We’re reminded of Hyrum’s Law, shown a xkcd comic on the matter, and Tony discusses this and charm updates, and the new ‘super-tox’ tool. Tony talks about the tool, gives us examples of how it was used, before moving to changes that will occur in the Ubuntu 26.10 development cycle. If we’d like to try super-tox, or have feedback on the approach, we’re asked to ‘get in touch’.

We’re told that “release notes get a new home, hardware support docs consolide, Zig makes its debut in the developer docs, llms.txt lands” and more. We’re given numerous links along with details of the work done. We’re also told a formal triage policy is now in place for documentation, and of a new workflow report that is expected to soon send weekly status reports.

How to Install MATE Desktop in Ubuntu 26.04 LTS

In this ‘how to’ blog, Ji m reminds us of the lack of Ubuntu MATE’s 26.04 LTS release following the stepping down of the leader developer [see UWN 937], and thus tells us how to install the full MATE desktop environment on a Ubuntu 26.04 LTS system. If we decide we don’t like it, we’re also told how to remove it.

Linux Matters - Passing the Gourd

Alan Pope, Mark Johnson and Martin Wimpress are hosts of this podcast. First topic is “Martin goes over why and how he’s stepping down from Ubuntu MATE after 12 years, and that the project is seeking new maintainers”. Martin also discusses responses to this ‘plea for help’, telling us a little about some of those who’ve put their hand up. The Ubuntu MATE Community Discourse is also covered, with it being closed down, with the data to be archived, with users ‘signposted’ to move to Ubuntu Discourse in the MATE area. Other topics are also discussed.

The IT Guy Show: Ubuntu Community: Years of “Just Works”

“Teaching a Linux course will humble you fast, especially when your students ask about apt and you realize the last time you logged into an Ubuntu server was when you were still a sysadmin. That embarrassing moment is what sent Eric looking for someone who lives and breathes Ubuntu every single day, and it led him to Nathan, a two-decade Ubuntu community volunteer who has been running booths, moderating Reddit, and serving on the Ubuntu Community Council since the early days of the distro. This episode is less a technical deep dive and more a conversation about what makes Ubuntu different at a human level. Nathan walks through the early days of the community, the real relationship between Debian and Ubuntu, what it looked like to set up a booth with plastic tablecloths from Party City at SCaLe 6x, and why the “distro wars” online are mostly theater compared to the genuine camaraderie between open source contributors behind the scenes. If you have ever wondered whether Ubuntu is still the right distro for someone just getting started or coming back after years on other platforms, this episode will give you the honest answer from someone who has watched the community evolve for more than twenty years.”
