Only ubuntu 23.10 uses 6.0 according to downstreams and that is EOL in a few

also 23.10 users will probably upgrade to 24.04 LTS so shouldnt affect anyone

Hi all
several of our release branches have the latest release from 2023
also there have been many fixes that need backporting
so i will start backporting and then making new releases.
ill probably do the branches which have had no release for longest
first. (limited to what is still supported)
