I think I may have found a fix. I would get this error and none of the above solutions would work.

W: GPG error: http://packages.medibuntu.org gutsy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 2EBC26B60C5A2783
W: You may want to run apt-get update to correct these problems

I opened up a text editor as root and began exploring the /etc/apt/ directory hoping to find the source of the problem.
Voila.
There is a directory called "sources.list.d/" and inside was a file containing the medibuntu information that was stumping apt-get.
I deleted the file and all was well once again.

Hopefully this helps.
