How to edit sudoers file in ubuntu

Question

I accidentally changed the mode of the file /etc/sudoers and added a line to the file.

Now every time I want to "sudo", I got a error message like "parse error in /etc/sudoers near line 21"

I can't login as a root also now. How can I solve this.

polkit doesn't help when you don't have a GUI. – Michael Hampton Nov 23 '13 at 18:16
