Ubuntu 25.10 "Questing Quokka" is now formally open for development.

Utkarsh Gupta of Canonical [1]announced that Ubuntu 25.10 is now open for development. Auto-syncing from Debian has begun as part of kicking off the new development cycle following last month's Ubuntu 25.04 release.

Ubuntu 25.10 should be a particularly busy cycle as developers work to land any big ticket items they want to get in for testing ahead of the very important Ubuntu 26.04 Long Term Support (LTS) release next April. Thus expect a lot of shiny new features in Ubuntu 25.10 from Canonical and the Ubuntu community.

Ubuntu 25.10 is expected to ship with the GNOME 49 desktop and all the latest Wayland and HDR goodies there and more. Based on the timing, Ubuntu 25.10 should be powered by the Linux 6.17 kernel with the kernel cycle likely aligning just enough for getting that newest upstream kernel version in come October. Ubuntu 25.10 will also transition from GCC 14 to the newly-released GCC 15 compiler stack. Plus there should be Mesa 25.2 graphics drivers and an assortment of other great software updates to find in this autumn 2025 Linux distribution release.

Ubuntu 25.10 should also be quite notable in [2]plans to use Rust Coreutils by default in place of GNU Coreutils. Ubuntu 25.10 will also [3]likely be using Dracut by default . Plus we'll see what other new optimizations and Rust changes may land this cycle.

Stay tuned for more details on Phoronix for the exciting Ubuntu 25.10 development cycle as new features land.
