IF you backed up all your important data BEFORE you did the upgrade, reinstall 20.04 from scratch. Many bad experiences taught me to ALWAYS back up everything to external media and ALWAYS do a fresh install. NEVER do an upgrade.
I will quickly defer to smarter people who can really answer your question. My way is cowardly but effective.

Hey @berninghausen, you may think it “cowardly”, but I call it SMART.
The only part I would slightly dis-agree with is “never do an upgrade”. If you have your backup and the upgrade goes south, you can always restore. On my laptop I went from Linux Mint 19.1 and upgraded to 19.2 and then to 19.3. Maybe you were not talking about upgrades within a release.
But I also upgraded from Linux Mint 19.3 to 20.0 with no ill affects. Of course, again I had my backup to restore if needed.

Thanks, easy. I frequently feel that the K.I.S.S. principle was developed just for me. Fresh installs are my way of keeping it simple.
