I'm trying to upgrade ubuntu my ubuntu 13.04 to 13.10, but there is always this error:
Error during update A problem occurred during the update. This is usually some sort of network problem, please check your network connection and retry. W:Failed to fetch http://archive.canonical.com/dists/[distro]/partner/source/Sources 404 Not Found [IP: 18.104.22.168 80] , E:Some index files failed to download. They have been ignored, or old ones used instead.
It's not the internet connection problem. My internet works fine.... i have good connection.
Can someone help me with this problem? Thanx
