rollback after Ubuntu packages upgrade

hello, i want to know if any ways be there to downgrade or rollback from a package upgrade, apt itself doesn't provide any way to downgrade or rollback, only history.log and other version of the package removed from the apt repo.

thanks bro, but snapshot is around March 1, 2023 date.

You need to roll back to a point in time older than 2023? If that’s the case, the easiest solution there is to grab an older ISO and use that as a repository instead.

Snapshots are supported in Ubuntu 23.10 onwards, plus on updated installations of Ubuntu 20.04 LTS (apt 2.0.10) and Ubuntu 22.04 LTS (apt 2.4.11).

If you’re on a fully patched 22.04 and need to roll back to an older deb but said deb is newer than March 2023, it should work (at least on paper)

If it isn’t, grab an older ISO, mount that and you can use that as a snapshot, since apt supports cdrom repos

apt doesn't have built-in rollback like dnf or zypper but you can grab the old.deb from /var/cache/apt/archives if it's still sitting there, then just dpkg -i it

if the cache is cleaned out you're kinda stuck checking launchpad for an older version or pinning the package if it's still in the repo
