How can I fix the following error with sudo?

/etc$ sudo
sudo: /etc/sudoers.d is world writable
usage: sudo [-D level] -h | -K | -k | -V
usage: sudo -v [-AknS] [-D level] [-g groupname|#gid] [-p prompt] [-u user
            name|#uid]
usage: sudo -l[l] [-AknS] [-D level] [-g groupname|#gid] [-p prompt] [-U user
            name] [-u user name|#uid] [-g groupname|#gid] [command]
usage: sudo [-AbEHknPS] [-r role] [-t type] [-C fd] [-D level] [-g
            groupname|#gid] [-p prompt] [-u user name|#uid] [-g groupname|#gid]
            [VAR=value] [-i|-s] [<command>]
usage: sudo -e [-AknS] [-r role] [-t type] [-C fd] [-D level] [-g
            groupname|#gid] [-p prompt] [-u user name|#uid] file ...

Run pkexec chmod 0755 /etc/sudoers.d

pkexec will use a different method of using root permissions, bypassing the issue.
And the chmod will fix the permissions.

Run this 2 commands with (555) permissions:

pkexec chmod 555 /etc/sudoers
pkexec chmod 555 /etc/sudoers.d/README

Did you try going into recovery mode and switching the permissions back to 775 for sudoers? I tried it and it worked.

1) Get into Ubuntu Recovery

2) Do mount -rw -o remount /

3) Then chmod 775 -R /etc/sudoers and chmod 775 -R /etc/sudoers.d/.

This time it should work.

4) Then do a sudo apt-get install of any package to test before you leave recovery mode. Late reply but I encountered the issue recently and tried this. It worked fine atleast for the world writable issue.

  • What do you mean by "Get into Ubuntu Recovery"? Once I'm at the recovery menu do I select root? That gets me to a root shell that is in recovery but this doesn't seem to work. – Mark Kramer Mar 4 '17 at 0:34
  • I got sudo to work by using live USB, mounting in /mnt, and chroot /mnt – qwr Aug 24 at 23:10
