I recently installed Ubuntu 13.04 on my PC. I want to install Microsoft Visual Studio 2010, so I tried to install WINE.
I tried to install from the Terminal and from the Software Center. Both times, it failed in the middle of process. This is the error.
W:Failed to fetch http://pk.archive.ubuntu.com/ubuntu/dists/raring/main/source/Sources 404 Not Found W:Failed to fetch http://pk.archive.ubuntu.com/ubuntu/dists/raring/restricted/source/Sources 404 Not Found E:Some index files failed to download. They have been ignored, or old ones used instead.
How can I fix this?
