Canonical Blog:
The latest interim release of Ubuntu comes with compatibility enhancements at the silicon level, accessibility upgrades and a robust security posture that sets the stage for the next LTS.
Today Canonical announced the release of Ubuntu 25.10, codenamed “Questing Quokka,” available to download and install from ubuntu.com/download.
Alongside GNOME 49 and new default applications such as the Ptyxis terminal emulator and the Loupe image viewer, Ubuntu 25.10 introduces notable platform upgrades, from improved Bluetooth audio handling to expanded support for confidential computing features. Ubuntu 25.10 is the first to benefit from memory-safe implementations of “coreutils” and “sudo-rs,” as well as improvements in TPM-backed full disk encryption and support for nested virtualization on Arm.
Ubuntu 25.10 is a statement of intent for the next Ubuntu LTS in 2026. Canonical continues to deliver a resilient, performant Linux operating system trusted by individuals and enterprises alike, from makers and developers to Fortune 500 companies, across hardware from IoT devices to modern datacenters. I’m particularly pleased with the progress on memory-safe utilities, and the enhancements to our TPM-backed full disk encryption.
Jon Seager, VP of Ubuntu Engineering at Canonical
This Ubuntu release is also the first to coincide with a new format of the Ubuntu Summit, where viewers around the world can learn about the latest developments in Ubuntu and open source.
