[2023-03-23T21:57:30Z] <mutante> moscovium - apt-get upgrade (rt.wikimedia.org going into maintenance) T327068
[2023-03-23T22:00:53Z] <mutante> moscovium - apt-get full-upgrade ; apt autoremove ; replace buster with bullseye in sources.list ; repeat apt-get upgrade/full-upgrade etc. (https://wiki.debian.org/DebianUpgrade)
[2023-03-23T22:09:28Z] <mutante> moscovium - when doing an in-place upgrade from buster to bullseye and you replace the string in sources.list, you also need to replace "bullseye-updates" with "bullseye-security" in the security.debian.org lines - that this is needed is called a bug at https://shagain.club/index.php/archives/641/ -

Done! So the steps were ~:
systemctl stop rsync (after cleanup of migration stuff)
apt-get update (ensure first everything within buster is upgraded)
apt-get upgrade
apt-get full-upgrade
apt autoremove
disable-puppet 'dzahn' (stop puppet from messing with APT source files and other stuff)
vi /etc/apt/sources.list (s/buster/bullseye/g)
vi /etc/apt/sources.list.d/wikimedia.list
vi /etc/apt/sources.list.d/debian-backports.list
vi /etc/apt/sources.list.d/debian-debug.list
apt-get clean
apt-get update (an error appears that ""bullseye-updates" has no release file", fix with 's/bullseye-updates/bullseye-security but only in the lines including security.debian.org)
vi /etc/apt/sources.list
apt-get update (error gone)
apt-get upgrade (actual upgrade starts)
apt-get full-upgrade (the interesting part starts where you have to answer a bunch of questions which config files to keep and which to overwrite, puppet will of course again overwrite certain things after it's enabled again)
apt-get autoremove
shutdown -r now
run-puppet-agent (will revert some things, remove some old packages as well via base class)
22:38 < somiaj> !bullseye/updates
22:38 < dpkg> There is no "bullseye/updates" repository for security updates. To reduce confusion with <bullseye-updates> (which is for other bug fixes), security updates are distributed via the
<bullseye-security> repository "deb http://deb.debian.org/debian-security bullseye-security main". Note that you may also need to adjust your Default-Release and pinning settings for apt.
22:38 < somiaj> .. though when upgrading you should really read the release notes. https://www.debian.org/releases/stable/i386/release-notes/ch-upgrading.en.html
22:39 < somiaj> hmm, surprised the release notes don't mention the security change
22:40 < somiaj> https://www.debian.org/releases/stable/i386/release-notes/ch-information.en.html#security-archive -- oh nevermind it is there, just not where I expected itComment Actions

@joanna_borun @MoritzMuehlenhoff moscovium (rt.wikimedia.org) can be removed off the list (or rather, added to the list of things achieved in sprint)
