The problem is that because the permissions are wrong on the sudoers file, linux won’t let you run the sudo command!

To get around this press “Esc” at the grub loader screen when linux is booting and enter into the latest recovery mode. Then select the option that allows you to drop into a command line as root and type 

chmod 0440 /etc/sudoers

Then reboot and your troubles should be solved!
