As of the Ubuntu LTS release in 2020, the server documentation has moved to a different site, and will automatically update when changes are made to the discourse source code pages.
The Desktop links above are available in many different languages. They will be displayed in the preferred language specified by your browser. If the preferred language is not available they will be displayed in English. The Serverguide and the Installation Guide are available solely in English.
Unsupported releases are not shown here. See instructions for upgrading to a supported version.
Useful information: LTS details and release & end-of-life dates (for all versions).
