Could you provide more information about this install? When did you originally install Ubuntu? I thought that the minimum UID has been 1000 for several years.

The upgrade went smooth except that the installer asked me if it could make changes to /etc/login.defs. I thought it was supposed to not ask questions (and stall the upgrade if I was away from the computer), but I pressed yes and it continued. I pressed yes since I had not personally modified this file as far as I can remember and was not particularly attached to its contents. After reboot gnome-initial-setup wants me to create a new user. There is no (obvious) way to login with my old user, but Ctrl+Alt+F2 luckily worked---I could log in and all my files where still there. I tried changing UID_MIN in /etc/login.defs back to 500 from 1000 (I believe this was the change I was prompted about), but I still could not login graphically, so the /etc/login.defs change may have been unconnected to the bug. I was able to figure out that the offending program was called gnome- initial-setup and an "apt purge gnome-initial-setup" later I could log in as normal. I do not believe an average user could have figured this out (how many even know about the virtual terminals Ctrl+Alt+FX?).
