Ubuntu 25.10 Questing Quokka reached end of life

This version of Ubuntu, which was released on October 2025, has reached its end of life period. Ubuntu 25.10 Questing Quokka brought Linux 6.17, systemd 257.9, .NET 10.0, and various new versions of different packages. It’s a short term release that is supported for nine months, as opposed to long-term releases.

This means that the following will happen:

• Ubuntu 25.10 will no longer receive any new versions of packages.
• Security updates for different packages will also no longer be made for this version of Ubuntu.
• Official support will no longer cover this version of Ubuntu.

In order to continue receiving official support and new package updates, including security updates that will be distributed after July 2026, consult one of the upgrade paths, depending on the type of installation:

Ubuntu 26.04 LTS Resolute Raccoon is supported for 15 years total, including 5 years of mainstream support, which will include point releases that will be unveiled in the future, such as v26.04.1, which is expected to arrive in the second half of this year. We recommend that you upgrade your systems using 25.10 to this version to continue receiving updates and official support.
