[Software] Buster to Bookworm broke login

[Radjin]

Since I didn’t find another topic that seemed to fit I can guess not many made the stupid mistake of upgrading from Buster to Bookworm without going through Bullseye. I had an old stable system that I was doing general maintenance on and noticed, through webmin, that Buster was end of life. I looked up the latest and upgraded to Bookworm without checking to see if there was an update in between. This broke my login after a reboot. I know you far more experienced people out there will laugh at the noob move, but I will eat humble pie and ask for help, either fixing the broken parts or reverting back to the nightly snapshot.

I use BTRS and take a snapshot each night in the default snapshot directory. That is copied on to my archive drive which has every nightly snapshot going back years. The snapshot is replaced each night, so there is ever only one snapshot on the volume. I’m sure the archived snapshots cannot be directly restored, but they have a daily copy of all critical files in case I need them.

At this point, when I boot the system, it does not recognize my login, either user or root.

What steps can I take to either repair the broken login and possible other parts that the upgrade created, or restore the snapshot and then do a proper upgrade?

Thanks in advance for your help,

Radjin~

Please provide details of meaning of "broke my login". What exactly does, or does not, happen that should? Is failure on a GUI screen, or on a VT (e.g. Ctrl-Alt-F3 after boot for sure has completed).

The system boots to a login prompt. It does not recognize my login, either user or root. I don’t use a GUI. The WebServer nor SSH appear to be running as I cannot link to it from another computer or access the various websites. Ctrl-Alt-F3 has no visible affect.

I took a video of boot and grabbed shots of each page, so I could see all the failures and any others stats displayed. A lot of failures. They are in reverse order here.
