If you like commands, here is one that appends, with administrative  
privileges, the line "deb http://packages.mate-desktop.org/repo/ubuntu  
precise main" to /etc/apt/sources.list:
$ echo "deb http://packages.mate-desktop.org/repo/ubuntu precise main" | sudo  
tee -a /etc/apt/sources.list

Do not forget the "-a"! Without the current content of the file is *replaced*  
by your line.
