No, don't use sudo with graphical applications or you will end up with
root ownership of X files in your home directory which will cause you
problems later.  Use sudo nano or sudo vim or some other text based
editor.  For simply commenting out lines sudo nano will do the job.
Just use the keyboard to navigate.  When done use Ctrl-O, Enter to
save and Ctrl-X to exit.  Then reload the package info.
