I have been having trouble getting GUI Application Manager to refresh. It always stop at 2.11 MB downloading. I have to cancel it. I have been having this problems for months.

Also, doing apt-get update ends up with an error. It mentioned something about some URL unreachable or something along that lines. Of course apt-get install or App Manager install doesn't work. I think I can't resolved dependencies and has links to old locations, so install doesn't work.
