After making an Ubuntu update i can't login

[TimoG2]

Hello,
I made an Ubuntu update a few minutes ago and now i can't login anymore. After i typed in my password i get to a new screen and it says: Oh, no! Something has gone wrong. A problem occurred and the system can't recover. Please log out and try again.
I tried restarting my mac and ubuntu but nothing works.
Any suggestions?

After a long session i found the issue's. For anyone having this problem: get to the login screen and press ctrl + alt + F5 (if it doesn't work disable F1 F2 keys in keyboard -> keyboard shortcut settings in systemsettings on Mac. Then login with your username(default parallels) and password. Then execute journalctl -xb -p 3 to read logfiles. For me this was the fix:
sudo apt reinstall gdm3 ubuntu-desktop
sudo dpkg-reconfigure gdm3
sudo apt reinstall gnome-keyring libpam-gnome-keyring
sudo pam-auth-update (then press esc to get out of the screen)
sudo apt reinstall libpam-modules
sudo apt update
sudo apt --fix-broken install
sudo dpkg --configure -a
sudo apt full-upgrade
sudo reboot
