If you can't become root, then boot a live CD (preferably one that supports your accessibility requirements), mount the root file system of your Linux installation and edit etc/sudoers. Finally, reboot. See the sudoers (5) manual page for details if you don't know what's wrong with your sudoers file.Editing /etc/sudoers file is always a risk, so if you want/need to do it, instead of use directly the editor, I recomend to use 'visudo'.
you can if you want, I typically do personally, but its not really risky. For it to at be at all a problem you have to one not know the root password, which is a very bad situation, and two not be obeying the rule about keeping a root shell open until your changes are tested. If you don't have a root password on a machine you should fix this, and learn to keep the root shell open until the changes are tested. Trev
This command will check the syntax before you exit the editor and warn you so you can fix it. Normally 'visudo' will launch the editor you have defined by default in your envirnment settings (this is terminal stuff...): VISUAL or EDITOR. Which I think is nano in Ubunto and 'vim' in others... I'm not sure... But probably you want to use something simplier as GEdit. You can launch it doing from a terminal: VISUAL=gedit sudo -E visudo You can use the editor you preffer instead gedit, of course. The '-E' flag in 'sudo' is for using the user enviroment variables (as VISUAL). Once you have saved the file (actually a temporary file) and exit from the editor you'll get a message at the terminal about if the 'sudoers' file was changed successfully or if it's had syntax errors and need to be fixed before to be saved. I know this is now pretty stuff for not technical user, but editing the 'sudoers' is not a safe thing to do without knowing. I hope this will help.
