I'm running Linux Mint 14 (Nadia) 64-bit, everything is working fine except when I use the update manager.
I got an error:
Code: Select all
Failed to fetch http://ppa.launchpad.net/upubuntu-com/devel/ubuntu/dists/quantal/main/source/Sources 404 Not Found
Failed to fetch http://ppa.launchpad.net/upubuntu-com/devel/ubuntu/dists/quantal/main/binary-amd64/Packages 404 Not Found
Some index files failed to download. They have been ignored, or old ones used instead.
Is this a bad URL? I don't know what to do to fix this... So if any of you had the same problem and solved it, what's wrong?
