How can I fix a 404 Error using a PPA?
I'm quit new to Ubuntu and i still getting settled. But i came across an error that's been bugging me. Can't update
Failed to download repository information Check your Internet connection

They have been ignored, or old ones used instead
I've seen some of this problems around but still can't find out what is wrong :/ (using 12.04 btw)
Any help is really appreciated
thanks in advance
