I had the same issue on popos Cosmic alpha and I couldn't login to the desktop, kept getting error messages since it probably didnt finish upgrading before I powered down manually, so I had to hit
Ctrl + Alt + F2
Logged with usename and password into terminal
Some terminal commands that fixed it for me (not necessarily in this order)
I'm running Cosmic and have been having issues with updates through popshop. Running updates manually through terminal has been more reliable, otherwise i gotta run sudo apt full-upgrade every now and then to fix whatever broke with popshop upgrades.
