[ubuntu] source list errors

view story

http://ubuntuforums.org – I just installed 12.10 and I'm looking at Tweak's Source Editor. It is showing multiple, but not all, *-precise.list in the left column and the correct deb *quantal main in the right column. Is there a way to automatically update the left column to show the proper quantal name, or is this strictly a cosmetic error? Here is a partial detailed output of backend_helper.py: W:Failed to fetch http://archive.getdeb.net/ubuntu/dis...eb/Release.gpg Unable to connect to archive.getdeb.net:http: , W:Failed to fetch http://archive.getdeb.net/ubuntu/dis...amd64/Packages Unable to connect to arc (Hardware)
