Try selecting the main mirror in software sources (System>>Administration>>Software Sources, enter your password, then on the first page, change download from bar to either Main Server or United States server (or something close to that), reload when prompted, then after everything is updated, close out software sources (if it doesn't automatically close). Then, try it again.
