  Possible Extended LTS

3(1,2)

  updated by LLNG Team until dependencies are compatible. Don’t use backports unless you plan to update your system because backports are not covered by Debian Security Policy

4(1,2)

  around July 2023

5

  few days after release

  Ubuntu universe/multiverse branches are community maintained (so not maintained by Canonical), but in fact nobody considers LLNG security issues. See this issue for example
