Did you do “ls -l /usr/bin/sudo”?
Mine shows: “-rwsr-xr-x 1 root root 157192 Jan 12 12:10 /usr/bin/sudo”
Make sure it’s set with that “s” in the root permissins!
Also, could your /etc/sudoers file be corrupted? Might want to grab the one off the original. There are warnings a/b needing to use a special version of vi to edit it (called “visudo”) as one can corrupt it using just “vi” somehow, though I’ve never mucked mine up with vi. It should be “-r–r—– 1 root root…”.
