Thanks in advance.

Is that all you have in your sources?

Please use code tags for text output like that. I edited it for you this time. And you don't need to be root to view that file, only to edit it.

To do the upgrade as I posted above, you first need to comment out the "deb cdrom" lines by placing a hash mark at their start (#) and save the file.
