Trying to update Firefox, following instructions. Here is my results from executing the first line, done with copy paste:
barry@barry-desktop:~$ deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main No command 'deb' found, did you mean: Command 'debc' from package 'devscripts' (main) Command 'derb' from package 'libicu-dev' (main) Command 'dab' from package 'bsdgames' (universe) Command 'debi' from package 'devscripts' (main) deb: command not found
Not really a great start. Now what?
