How can I fix a 404 Error using a PPA?
I get the following error message when I try to check for updates:
W:Failed to fetch http://ppa.launchpad.net/dists/https/ppa/ubuntu/natty/source/Sources 404 Not Found W:Failed to fetch http://ppa.launchpad.net/dists/https/ppa/ubuntu/main/source/Sources 404 Not Found W:Failed to fetch http://ppa.launchpad.net/dists/https/ppa/ubuntu/natty/binary-i386/Packages 404 Not Found W:Failed to fetch http://ppa.launchpad.net/dists/https/ppa/ubuntu/main/binary-i386/Packages 404 Not Found E:Some index files failed to download. They have been ignored, or old ones used instead.
What can I do to correct this? This is a new installation of Natty. I installed updates only once, and subsequently I have only received this error message when trying to check for more updates.
