Ubuntu Project docs: That’s a wrap!

Robert Krátký provides another update on Ubuntu Project docs telling us this “update wraps up the 25.10 cycle and the bulk of main work on the Ubuntu Project docs”. Whilst we’re told there is still more to do, with more blog updates to come, a major milestone has now been reached, with the ‘major effort’ undertaken back in May now completed. A list of the entire Ubuntu Projects docs series is provided, before Robert gets down to the fortnightly progress report. Robert lists the contributors and what was done, before getting to a summary of the last six months work, in this detailed post.

Introducing architecture variants: amd64v3 now available in Ubuntu 25.10

Michael Hudson Doyle reminds us that back in 2023 he wrote an article on amd64/x86-64 architecture, giving us the ‘levels’ (v2-v4). This blog post gives us details of a new architecture variant that targets x86-64-v3 in Ubuntu 25.10. We’re given more details, including some benchmarks, and how we can enable amd64v3 on our systems.

[Ubuntu Studio] Upgrading from 25.04 to 25.10

The Ubuntu Studio team have reported a bug appearing when users of Ubuntu Studio 25.04 (or Kubuntu 25.04) attempt to upgrade to 25.10 that can result in an empty notification. Details are provided, including that Erich Eickmeyer has uploaded a fix that has been accepted by the SRU team, and for now sits in plucky-proposed. We’re told how we can achieve the upgrade if we don’t want to wait, but with 90 days remaining to upgrade there is no need to hurry. An apology for the inconvenience is given.

Getting the Most Out of Our Discourse: A Fortnightly Series of Thoughts, Ideas, Tips & Tricks

‘This will be the first post in a fortnightly series intended to guide users with tips and tricks to get the most out of their experience here. In the beginning… Almost one year ago, I had never even heard of Discourse as a platform for conversations and support. Nearly one year later, I consider myself to be somewhat more than a novice but still learning every day. In fact, my journey of discovery has been very enlightening and I want to share some of my thoughts and findings with the community in the hope that you, too, will be motivated to learn more about this amazing software and our wonderful Ubuntu Discourse…’ Rubi1200

Canonical CEO says no to IPO in current volatile market

Steven Vaughan-Nichols tells us more about his interview at Ubuntu Summit 25.10 with Canonical CEO Mark Shuttleworth, this time focusing in on the IPO (Initial Public Offering) prospect.

Linux vendors are getting into Ubuntu – and Snap

Liam Proven notes that multiple “Linux-adjacent” vendors presented at the Ubuntu Summit 25.10, with many offering official Snap packages. Liam writes that these companies found working with Canonical simplified software distribution, with this post giving us details of what was presented at the Summit in this regard. Liam also discusses some major “Linux freeware apps” which don’t use snap packages, and what they use instead.

Ubuntu Unity In Need Of More Developers To Survive

Michael Larabel reminds us (see UWN 915) that the Ubuntu Unity flavor is in “a difficult position and at risk” and is seeking more community developers. We’re reminded why Ubuntu Unity 25.10 didn’t release with quotes from Maik, and that the team is still hopeful for Ubuntu Unity 26.04 LTS.

AMD Updates Zen 3 / Zen 4 CPU Microcode For Systems Lacking Microcode Signing Fix

Michael Larabel tells us about AMD’s uploading of new “Family 19h CPU microcode for Zen 3 and Zen 4 processors to the linux-firmware.git”. We’re told that normally these uploads don’t include a changelog, but did this time with a README updated. Michael reminds of a CPU microcode signature verification vulnerability, with a link should we need more, and told BIOS needed to be updated. This change mitigates much of the issue on hardware that didn’t get a BIOS update from their vendors.
