My installation is broken

UNIT LOAD ACTIVE SUB DESCRIPTION
0 loaded units listed.

If you shutdown again do you still see those errors? Those messages are actually from when you last started, you just see them on shutdown so they may be fixed now.

Yes, I still see them and I cannot restart or shutdown properly without using the power button as the screen keep stuck showing those errors.

What does systemctl status snapd show?
