Sudoers File Permissions Error
Recently, when I've been trying to use any "sudo" commands in the Terminal, it's been rejecting me and coming up with this error:
sudo: /etc/sudoers is mode 0666, should be 0440
sudo: no valid sudoers sources found, quitting
And then putting me back to the ordinary command line. This is urgent, as it renders in particular the "sudo apt-get" and "sudo -i" commands totally invalid; I can't install apps from the command line. I have absolutely no idea what caused this, neither do I have any idea how to fix it (probably something to do with chmod, but when I try that, it rejects me) - so any help would be greatly appreciated.
Thanks!
Re: Sudoers File Permissions Error
Easiest way to fix it would be from install CD or bootable iso on USB. But when you sudo chmod it from there, you need to begin with the path to your mounted internal hard drive before the etc/sudoers.

boot the os in recovery mode(at boot time keep the shift key pressed untill u see the grub menu, press again shift to see the recovery menu) and from there select shell prompt as root user:
once u login do :
Code:
chmod 440 /etc/sudoers
reboot now

How do I do that?
EDIT: Forget it, I'm moving to Mint.
