I want to downgrade my ubuntu version 22.04 to 20.04. I'm facing lot of issues since I upgraded the system to 22.04 like,

  1. System is hanging sometimes
  2. Battery is draining too fast.
  3. Lock screen delay

    There's no downgrade path, only reinstallation. Aug 25, 2022 at 10:05
  • How are we to know what backup strategy you're using. Ubuntu release-upgrade tools will upgrade you to a later release; downgrading is done via whatever backup strategy you put in place.

  • @ChanganAuto you mean I have to reinstall 20.04?

    and why is this tagged 20.10? @Satya yes that is what he means. I would suggest a re-install of 22.04 though if you going to re-install. 1 and 2 might be due to the upgrade. 3 is a feature that needs fixing (wayland + open source driver are the issue): it will disappear when you use the 3rd party driver if you have nvidia or when using xorg instead of wayland

    Better to troubleshoot the problems you have now, even backup personal files and install from scratch just to rule out some rare problem with the release upgrade. But if you really want 20.04 then yes, you'll have to install it. Aug 25, 2022 at 10:11
