Frequently Asked Questions

Does this mean the update package itself is broken?
It can be, but it's also frequently caused by a corrupted update cache on your end — clearing SoftwareDistribution and retrying resolves it in many cases without the update package itself being at fault.
Will this error recur on the next update too?
Not necessarily — if the cause was a temporary cache corruption, clearing it resolves the issue for future updates as well, not just the current one.
