I have Ubuntu 12.10 on my client system. I have an error
/etc/sudoers is owned by uid 1000 should be 0. I tried booting from an Ubuntu live CD and tried:
sudo chown root:root /etc/sudoers sudo chmod 440 /etc/sudoers
sudo chown 0.0 /etc/
But it is not working. It continuously gives an error:
sudo : /etc/sudoers is owned by uid 1000 should be 0.
How can I resolve this problem?
