Ubuntu 25.10 'Questing Quokka' is out now

Canonical today launched the Ubuntu 25.10 'Questing Quokka' release, bringing with it many advancements across the Linux desktop. This is an interim release so it will only be supported for 9 months until July 2026. Releases like this are work towards the next LTS (long term support) which will be due with Ubuntu 26.04 next April.

With the release you get Linux kernel 6.17 and Mesa 25.2.3 with all the latest goodies from performance improvements to new hardware support. There's some major changes with this release like Ubuntu's session being Wayland-only, suspend-resume support has been enabled in the proprietary NVIDIA driver, new default apps for the image viewer and terminal, TPM-backed Full Disk Encryption recovery key management and much more.

A large part of user-facing updates are thanks to the update to GNOME 49 which has various new features and overall improvements to the desktop.

You also get various app and library updates, taken from the release notes:

• Firefox 143.
• LibreOffice 25.8.
• Audacity 3.7.1.
• GIMP 3.0.4.
• BlueZ 5.83.
• Pipewire 1.4.7.
• OpenSSL 3.5.3.
• GCC 15.2, binutils to 2.45, and glibc to 2.42.
• Rust toolchain defaults to version 1.85 while 1.88 is now available.
• LLVM defaults to version 20 while 21 is now available.
• OpenJDK defaults to 21 (LTS), while version 25 (LTS) and an early access snapshot of version 26 are now available.

A lot more comes with this release across all the different desktop flavours like Kubuntu, Ubuntu MATE and the others.

I'll be soon going through upgrading my Kubuntu install to 25.10. Hopefully it goes smoothly…
