There are 2 types of Ubuntu releases: Interim and LTS. Each Ubuntu LTS is maintained for 10 years total: 5 years of standard support + 5 years of ESM. Interim releases are maintained for 9 months.

For the Ubuntu release cycle please see: The Ubuntu lifecycle and release cadence.

We are happy to provide hosting for the following projects via the cdimage server. While they are not commercially supported by Canonical, they receive full support from their communities.

The cdimage server also hosts releases of other Ubuntu images not found on this server, such as builds for less popular architectures and other non-standard and unsupported images. For Ubuntu Desktop and Server on popular architectures, please see the links above instead.

Ports, Unsupported, and Experimental Images for Ubuntu

Your comments, bug reports, patches and suggestions will help ensure that our next release is the best release of Ubuntu ever. If you feel that you have found a bug please read:

  https://help.ubuntu.com/community/ReportingBugs

Then report bugs using apport in Ubuntu. For example:

  ubuntu-bug linux

will open a bug report in Launchpad regarding the linux package.

If you have a question, or if you think you may have found a bug but aren't sure, first try to reach out on one of the communication channels. Matrix is the go-to for instant chatting, while Discourse would be more approriate for long discussions in a more asynchronous way. Otherwise you can still join the #ubuntu IRC channel on Libera.Chat, send an email to the Ubuntu Users mailing list, or find some help on the Ubuntu forums:
