Its an error at Apples end nothing wrong with your system. Usually shows up when Apple pushes a lot of updates at once. Wait a while and try again but it may take overnight before it clears up.
If your desperate for the updates and its not an App Store purchase you can usually find the dmg file of the update on the Apple support site. Search around.
