On further thought, I believe that this is more appropriately handled as a support question than as a bug. I believe the cause of this is an errant "sudo" in your sources.list file, which is what the "grep" command from my previous comment would hopefully confirm. In that case, we can fix this for you by helping you identify where the problem is, and removing that line (or just the "sudo" part).
