I have a problem.
I was running bash in my terminal and when I executed the mv command, I got an error saying exec: mv: permission denied. I thought it was like my other permission errors, and so I ran sudo mv file folder, which gave me the same error.
I went to google the problem, but Firefox couldn't open, because of permission errors.
Because of all this, I rebooted (which worked, strangely, so it seems to only affect my user)
But X11 hanged when starting, so I switched to a TTY. (tty2 if that helps) I typed in my username and password, but my shell wouldn't start because of (you've probably guessed by now).
I would log into another user, but I only have the one and root doesn't have a password.
I'm writing this from my phone, but my computer's running Linux 5.8.34-generic Ubuntu MATE 20.10 and my own desktop environment.
Update:
I've installed Kubuntu now. That makes it the ninth Linux distribution I've installed in six months... I have a separate /home partition and a script for generating scripts that reinstall all my packages.
