When I type sudo <command>
in terminal I get sudo: unknown uid 501: who are you?
and when I type su
I get su: who are you?
I think I must have changed super user permissions somehow on my personal machine. I'm not able to use sudo commands now, and I've not been able to find any helpful solutions. Do I have to do something with my /etc/passwd
file? Can I even modify that?
FWIW - I simply had to install (via restart) the automatic updates that were downloaded and it was fixed. Logging out and back in didn't work.
It appears that simply restarting iterm2
may be sufficient, too, so that's probably a better place to start.
