Public bug reported: After enabling the -proposed ppa in Hirsute (21.04) I'm getting the following error:
ubuntu@hirsute:~$ sudo su - sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set ubuntu@hirsute:~$ ls -l /usr/bin/sudo -rwsr-xr-x 1 2001 2501 190952 Feb 10 11:42 /usr/bin/sudo I had a root session open so I could fix it by manually setting user and group ownership back to root. After that I noticed that also /usr/lib/sudo/sudoers.so had the wrong ownership: ubuntu@hirsute:~$ sudo su - sudo: error in /etc/sudo.conf, line 0 while loading plugin "sudoers_policy" sudo: /usr/lib/sudo/sudoers.so must be owned by uid 0 sudo: fatal error, unable to load plugins I manually fixed also this one and now my system seems to work normally. ** Affects: sudo (Ubuntu) Importance: Undecided Status: New ** Affects: sudo (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: sudo (Ubuntu Hirsute) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915779 Title: sudo: bad onwership of /usr/bin/sudo and /usr/lib/sudo/sudoers.so (2001:2501) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/1915779/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
