No need to apologise @Timpani, we all started somewhere.
You’re able to access the log of previous sessions. This command here, accesses the last 25 lines (tail -n 25) of the previous session’s log (-1) :
journalctl -b -1 | tail -n 25
To access two sessions ago (-2), adjust the command to:
journalctl -b -2 | tail -n 25
And so on…
Hopefully those will tell us what the system was trying to do, or got stuck on.
