    There is no downgrade option, you have the option of restoring your backups OR re-installing the older release, either way Ubuntu 20.10 is EOL & thus unsupported here as off-topic. Ubuntu 20.10 had a single release-upgrade option anyway; to the next release which was 21.04 anyway; 21.04 likewise only to 21.10... and not to the end of the two year development cycle (20.10, 21.04, 21.10 & 22.04 being the same full two year development cycle which ends in the LTS) – guiverc Jan 09 '24 at 06:35

    Ubuntu 20.10 (along with all flavors) is End-of-Life and thus unsupported on this site (https://askubuntu.com/help/on-topic), and many other Ubuntu sites, unless your question is specific to moving to a supported release of Ubuntu. https://fridge.ubuntu.com/2021/06/18/ubuntu-20-10-groovy-gorilla-reaches-end-of-life-on-july-22-2021/ https://help.ubuntu.com/community/EOLUpgrades – guiverc Jan 09 '24 at 06:35

    This is an XY Problem. Why do you want to downgrade? If there is any issue with 22.04, we can help troubleshoot it. Note that 20.10 has reached end of life, and will not receive upgrades, and may contain security vulnerabilities. – Archisman Panigrahi Jan 09 '24 at 06:38
  • I would not recommend this option (especially not to 20.10 or any EOL release), but you can re-install non-destructively Ubuntu Desktop systems, which includes going backwards (to an earlier release) however there are many potential complications when going backwards. You didn't specify if desktop or server install; but I write about non-destructive re-installs in this answer ( https://askubuntu.com/questions/446102/how-to-reinstall-ubuntu-in-the-easiest-way/1451533#1451533 ) and do mention going backwards too (though only touch on it & the 'homework' you should perform first) – guiverc Jan 09 '24 at 09:54
  • Rather than going back to 20.10; IF you're using a Desktop system, you could consider going back to Ubuntu 20.04 LTS Desktop.... but what @ArchismanPanigrahi suggested (in the XY Problem) is what I'll suggest exploring FIRST !! If you're not aware of what I'm touching on here though (non-destructive re-install) you'll likely not know how to predict & plan for backwards problems should they occur... also my answer doesn't touch on 3rd party apps (as they vary on packager/source differing to Ubuntu repository software in rules) – guiverc Jan 09 '24 at 09:57
