Thomas Ward has published an update about the future of the Ubuntu MATE project, which did not have a 26.04 release with the other Ubuntu flavors in April:

There is a new team working on Ubuntu MATE who have stepped up to help take over flavor management. They haven't formally introduced themselves yet, but I can safely say that other developers HAVE stepped up for the future of the MATE flavor, despite its prior team lead having stepped down.

[...] Ultimately, this means that they are working to cover the missed items and gaps, and may quite possibly have a 26.10 release in October of 2026, which I believe they most likely are targeting.

This also means that bugs in the MATE environment and in packages they normally would have shipped had they have a 26.04 release are still going to get attention and fixes. So, effectively, nothing has changed. The only difference is that there was no 26.04 installer image released.

For those looking to install a MATE desktop on a "clean" install of Ubuntu 26.04, Ward suggests installing Ubuntu Server and then installing the ubuntu-mate-desktop package.

Trusted publishing is an authentication mechanism that relies on short-lived credentials to reduce the risk of supply-chain attacks. At the 2026 Open Source Summit North America, Mike Fiedler walked the audience through why trusted publishing exists, how it works, and made the case for its adoption. It is not a silver bullet against all attacks, but it does offer protection against theft of long-lived credentials used to publish to package registries.

The Asahi Linux project, which brings Linux support to Apple Arm-based Macs, has warned its users not to upgrade to the macOS 27 "Golden Gate" beta.

Apple has changed how the boot picker and Startup Disk applications detect valid OS boot volumes. When using either from macOS 27, your Asahi partition will not be visible! We believe this to be a bug, and have filed a report (FB22994760).

If you have already upgraded to the beta and noticed that your Asahi partition has disappeared, do not stress. Your Asahi partition is still there, and you have not lost any data.

The Asahi Linux installer has been patched to prevent use with macOS 27 for now, but any users already bitten by the change will need to use macOS 26 to restore access to Asahi Linux.

Greg Kroah-Hartman has announced the release of the 7.0.12, 6.18.35, and 6.12.93 stable kernels. Each contains important fixes throughout the tree. Users are advised to upgrade.
