12.10 Sorftware Updater Error

[Ron McIlvaine]

I am having a problem with the Software Updater in Ubuntu 12.10. What a nightmare updating from 12.04 to 12.10. all the other things are fixed but when I run the Software Updater, after scanning many files I get this error.

W:Failed to fetch http://ppa.launchpad/gnome3-team/gnome3/ubuntu/dists/quantal/Release.gpg Something wicked happened resolving 'ppa.launchpad:http' (-5 - No address associated with hostname)

Any ideas?

Those URL's are trashed. You can post your sources.list if you would like to try to save them or you can just cut your losses and remove them.

In terminal enter:

cat /etc/apt/sources.list

Or to remove them:
