[ubuntu] Updating Problems (plus a couple more (that may be possibly related)

view story

http://ubuntuforums.org – Hello fellow forum lurkers, I am currently running Ubuntu 12.04 and I seem to be having problems updating and various other problems that my stem from the updating one (I'm not sure). So, I'm getting an error when I try to update, I use the Update Manager, get an error, so I go to the Terminal, update there, and get the same answer. It says that the package lists or status file could not be parsed or opened. I've also tried disabling some of the repos that I know I don't use and changing the server location to the Main Server, but nothing has changed, with the exception of it returning erro (Hardware)
