I can't apt-get update, upgrade or install on one PC I tried to apt-get install quake2! Don't ask, my kids at home were bored. Anyway, when I try to apt-get anything it says it can't and I must fix it with dpkg --configure -a. This thing keeps getting stuck downloading a none-existent file from www.blizzard.com and fixes nothing! What can I do about this?

TIA,
