Recently I had to change the folder permissions of /usr
folder. Now the whole sudo
is not working. If I try to update my system using this command:
sudo apt-get update
I get the following message:
sudo: /usr/lib/sudo/sudoers.so must be only be writable by owner
sudo: fatal error, unable to load plugins
So I tried to change the folder permissions by opening Nautilus as root by using this command
gksudo nautilus
But nothing happened. Nautilus didn't open. This is an emergency as the whole of sudo
is not working. when I tried searching the solution from Google many suggested re-installation. I don't prefer re-installation. so is there any other solution?
