It seems that Qt 6.3 and some PHP plugins are not usable under Ubuntu 22.04. Is there a way to downgrade to 21.10 (where I came from) ?

I searched in the Update manager but I found nothing about. Looking on the Internet most of sources just suggest to reinstall everything from scratch.

But I don't think there is no way just to undo an upgrade!

  • If you're talking about a desktop release; you can upgrade via re-install or just re-install an existing Ubuntu desktop release (including flavors) and use this to change release. I'm involved in QA-testing, and often perform this, we currently have dailies for 20.04, 22.04 & kinetic (what will be 22.10 on release), meaning I can make the existing install whichever I install & I verify that my data remains, and manually installed packages are auto-reinstalled... There are complications if using 3rd party apps, even specific apps (when going backwards) - but I'm doing this very often

  • @guiverc since I'm working on a remote (desktop) machine, i cannot easily reinstall. I hoped there is something like dist "downgrade"

There is no such thing unless you created it yourself (ie. made a full system backup).

The current options are:

A suggestion: when installing create a post install script with all your manual alterations (installing, removing software, changed gconf settings, make a backup osf file you edit to a safe location so you can copy it back into the system) so you can execute this script after every install. One time a bit of work but very useful in the long run.
