I have a question which derived from a comment I got to another question. I know that LTS Ubuntu versions have support for 5 years so that means that Ubuntu 16.04 is supported up to 04/20.
If I replace the GUI of Ubuntu with another not supported version like mate (which I have done) without formatting is this considered an action that breaks the system and, thus, it is now considered Ubuntu mate instead of Ubuntu or not?
mainis officially supported (and mayberestricted, but canonical depends on the original maintainers here),mate-desktopis inuniverse. If you installuniverse/multiversepackages it does not affect the support status of packages frommain. See also. – pLumo Apr 24 '20 at 08:41
