"Oh no! Something has gone wrong." after upgrading to 20.10

That's what I'm doing right now. Once that's finished, I'll blow away the non-functional 20.10 and reinstall 20.04.1

Excellent - Backups are a lifesaver.

Your 20.10 was non-functional following an upgrade, it may be fine for you freshly installed.

However, I always remain on LTS releases for daily use and then use a separate partition to explore 20.10 and subsequent releases until the new LTS is available.

I do the same. The wording on the upgrade notice was vastly misleading. As I said, I had my system set for "LTS releases only" yet this upgrade notice popped up. So I went ahead and allowed the upgrade. At some point during the upgrade, there was a nearly subliminal notice that the rebuild of NVIDIA (390 I think) failed with an error of "10". Things went downhill from there until I tried to reboot. Then I got the "you're dead" notice.

Yes: get everything backed up and off of that machine if possible.

I set my system notification of new Ubuntu version to Never, because the release dates are easy to remember.
