TFW after the OS upgrade you're greeted with a black screen with a cursor blinking in the upper left corner of your screen, the computer seems unresponsive to all keystrokes except CTRl-ALT-DEL, so you login with ssh with your pocket computer (we all have ssh enabled, right? (if that didn't work you would've tried messing with Grub kernel command line to boot into a different run mode)) and checkout "journalctl -b" to see what failed, notice PAM seems unhappy about something which apparently caused the login program to crash, so you (no LLM) search for the error message and helpfully land on a post that describes the exact issue and how to get out of it, and you apply the arcane commands, reboot with login repaired, and consider this an uneventful OS upgrade.
