it seems like it's trying to upgrade from the cd rom not from the online repositories. try to comment out the cd rom line from your sources.list file:


gksudo gedit /etc/apt/sources.listsee the line at the top that says cd-rom? put a # in front of it, then save, close, and try 'sudo apt-get update' again
