What's the error, exactly?

What to Try:

A. Apple's Servers being Down:

For the past week, Apple's servers have been intermittently down. So, you may need to try later on.

B. Disconnect form a VPN:

Are you connected to a VNP? If so, disconnect from it, trying once more.

C. Update Using a Computer:
