404 Error When Trying to Update

[Nick56x]

I am not exactly new to Ubuntu, but I am at the same time. I have never really had an issue with this before, but whenever I try to update my Ubuntu setup with sudo apt-get update, I get the:

W: failed to fetch

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/raring/main/binary-amd64/Packages  404  Not Found
W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/raring/main/binary-i386/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

I've looked and looked, and I can't figure out how to remove those. Can I get any suggestions? I would prefer to remove it from the command line if possible.

Raring Ringtail reached End Of Life on January 27, 2014 and its repos have been moved. I suggest a fresh installation of a currently supported version 12.04.4 or 14.04.

Raring is End of Life.
Update to a supported release
https://help.ubuntu.com/community/EOLUpgrades

Hope that helps.

Edit: To add, what is the whole output for apt-get update.
Is it all for raring, or is the raring reference only for the extras repos?

Hm.. I guess I will have to do a complete reinstall. I didn't want to, but it seems like the only way to fix everything.

Thanks for pointing that out.
