I want to upgrade to 12.04 but everytime I check for new updates this message shows up. "W:Failed to fetch http://us.archive.ubuntu.com/ubuntu/...-i386/Packages 404 Not Found [IP: 188.8.131.52 80]
, W:Failed to fetch http://wine.budgetdedicated.com/apt/...-i386/Packages 404 Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead."
It tells me to check my internet connection when I am connected just fine. I want to get this problem fixed before I upgrade so that everthing runs smoothly. What do I do to fix this?
