Public bug reported: Happened during upgrade of Ubuntu from 17.04 to 17.10. Stepped away from desk; when I came back I was locked out. I didn't recognize the lock screen. There was no way to log back into the session, no password prompt etc. I switched to a VT and monitored top for a while: "artful" was minimally active, but never about 2% CPU and memory never changed; I guessed it was waiting for a user prompt which I'd never be able to give, so I rebooted. I got this error on boot.
The system is now usable. I've done `dpkg configure -a; apt upgrade` and it's all working as I'd expect.
