Er. Depends on display server -- Wayland makes it more complicated --
but you can use your GUI editor of choice.

Open a terminal.
Do ``sudo -s'' to become root.
Navigate to the file, e.g. ``cd /etc/apt''
Open the editor, e.g. ``gedit sources.list''

That's what I do.

If apps running as root don't have permission to access the graphics
display, which I think is the default on Ubuntu but isn't on (e.g.)
openSUSE, you can add it with ``xhost+''

If you want a nice friendly GUI-like editor for the console, my
favourite is Tilde:
