A update failed and now my sudo powers are gone!

You don’t seem to have sudo privileges. Try the following things posted in the link below. Of course with your username instead of wolf.

Or do as @thefrog said. Both paths are viable.

Weird, some people got this bug over the last few days.

[Username] is not in the sudoers file and won't add

@Too_Dumb_For_This Did you say you could get to a root shell with su? If positive, get a root shell and then do: sudo nano /etc/sudoers.d/wolf Put in: wolf ALL=(ALL) ALL Press Ctrl-O, Enter, Ctrl-X to save the file and exit nano. Press Ctrl-D to exit the root shell. Now try your sudo.
