[1](1, 2) Possible Extended LTS
[2]updated by LL::NG 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
[3](1, 2) few days after release
[4]Ubuntu universe/multiverse branches are community maintained (so not maintained by Canonical), but in fact nobody considers LL::NG security issues. See this issue for example
