The Lubuntu project has announced the launch of Lubuntu 26.04.

The new long-term support release will receive security updates for three years. Lubuntu 26.04 ships with LXQt 2.3 and migrates some of its low-level program to Rust. "What's new since 24.04 LTS? LXQt 2.3 is now shipped by default. More information on its release can be found here: 2.3.0. 2048-qt is somewhat broken in Ubuntu 26.04 and therefore was removed from Lubuntu. See the Resolute Beta release notes for details. Many of the GNU coreutils were replaced by Rust equivalents in Ubuntu 25.10.

The traditional sudo system was similarly replaced with a Rust rewrite. Ubuntu 26.04 is the first LTS release to ship with Rust-based coreutils and sudo. See the 25.10 release notes for details. Lubuntu 26.04 is the first LTS release of Lubuntu to ship with a primarily Qt 6-based environment. Qt 6 applications should now be themed nicely, instead of looking somewhat drab like they once did. Recent versions of LXQt also come with a much improved application menu, Fancy Menu, which we have switched to. We also use Kvantum as our theming engine instead of Breeze."

Additional details can be found in the project's release announcement.
