Thanks a lot for the script. I'm just having a problem with the key for Banshee though. When using Update Manager it throws out the following error message:

Code:
W: GPG error: http://ppa.launchpad.net intrepid Release: The following signatures were invalid: BADSIG 4874D3686E80C6B7 Launchpad PPA for Banshee Team
Any ideas?
