General Community News

Resolute Snapshot 2 released

Utkarsh Gupta on behalf of the Ubuntu Release team tells us the “second successful publication of the monthly snapshot” is available for download and testing. We’re given links to download & test it, told some teams have already started filling in details for their 26.04 release notes, and reminded these aren’t ‘production ready’ releases. We’re also told why it’s being released a week earlier than planned, with the next snapshot scheduled for January 29, 2026.

SRU Freeze for End of Year 2025

Andreas Hasenack alerts us that there is an SRU freeze from December 17, 2025 until January 6, 2026 due to fewer staff available over the holidays. Special cases may still be approved, but there will be no regular SRU shift from December 22 until January 5.

Ubuntu Circles! (LoCo) News

Ubuntu UK Community Social Event – Southampton Recap

David Potter tells us a “brilliant time” was had at the Ubuntu UK Community social on November 30 in Southampton. We’re shown a photo, told people are looking forward to more events and to ‘keep an eye out’ for notices. We are invited to ‘jump into conversation’ here on Ubuntu Discourse or on Matrix.

Addressing Linux’s Missing PKI Infrastructure

Jon Seager tells us the LWN recently featured an article that highlighted issues surrounding “traditional Public Key Infrastructure (PKI)” usage. This article tells us how this will be solved with a partnership with rustls maintainers Dirkjan Ochtman and Joe Birr-Pixton, giving us details. The problem is defined, including differences between Windows and macOS; a short-lived credentials solution is presented. We’re told of the work to be done in the next few months, with thanks being given to Mozilla for their work on CRLite. We are given many links if we want to learn more. This is a somewhat detailed post.

Spec: Make ISO in livefs build

Michael Hudson Doyle tells us that livecd-rootfs will be relied on for building ISO livefs; this will remove reliance on ubuntu-cdimage and debian-cd. We’re given the rationale for this change, the specification (current and changes), and more. We’re also walked through a discussion on risk points.

Call for testing gemma3 inference snap

Farshid Tavakolizadeh reminds us of inference snaps that was announced at the Ubuntu Summit, and tells us of feedback received which has led to changes. This post announces a new snap “bringing Gemma 3 model optimization to embedded and desktop environments”. This post gives us details: gemma3 snap, arm64 and amd64 optimizations, and usage of CUDA. Feedback can be left on this post, or at the Github discussion page provided.

Ubuntu Insights - How telemetry is changing on Ubuntu Desktop

Jean Baptiste Lallement tells us that Ubuntu Report is being phased out, and replaced with Ubuntu Insights for handling anonymous telemetry collection. We’re told there will be no change for most users, with telemetry “strictly opt-in”. We’re told of the data collected, and told past consent (to Ubuntu Report) will not “carry over” to Ubuntu Insights. Jean “explains why telemetry exists, how it is changing, and what to expect beyond Ubuntu 25.10”. Thanks is given to Kat Kuo for “making this project happen”.

Coming to Ubuntu Studio 26.04 LTS: Three Layouts. Help Us Pick The Default!

Erich Eickmeyer talks about Ubuntu Studio’s panel placement, and gives a brief history of it since Ubuntu Studio 12.04 LTS. We’re walked through three options that may suit different Ubuntu Studio users, and asked which of these options will best suit our own usage of Ubuntu Studio. A survey is provided that may change the default layout for Ubuntu Studio 26.04 LTS when it releases.

Ubuntu docs: together in electric dreams

Sally Makin updates us on “documentation-land” in the last two weeks. Details covered include hardware support docs, Ubuntu policy, the new Wiki, Pro for WSL, and some adventures in AI. We’re reminded that Project docs have a ‘well stocked issues list’ that is being worked on, and we’re welcome to contribute.

Ubuntu 26.04 Will Look More Like Vanilla GNOME

Joey Sneddon writes that Ubuntu 26.04 LTS may appear closer to upstream GNOME than prior releases due to the Yaru theme team undertaking a refactoring of their GNOME Shell stylesheet. Joey gives us some details of what has been done in the past, and how “inconsistencies can creep in”. These will be reset with this refactoring. Joey provides screenshots to help illustrate his points, and does stress that “Ubuntu’s distinctive branding isn’t going anywhere”.
