The Update Manager is giving me a problem. Each time I hit the Check for updates button, I get the following error:
W:Failed to fetch http://ppa.launchpad.net/weather-indicator-team/pp/ubuntu/dists/natty/main/source/Sources 404 Not Found
W:Failed to fetch http://ppa.launchpad.net/weather-indicator-team/pp/ubuntu/dists/natty/main/binary-i386/Packages 404 Not Found
E:Some index files failed to download. They have been ignored, or old ones used instead.
I re-install the Update Manager and then it works properly, the same issue was with the Software Center I did the same and it worked. Any help?
