1511 to 1607 Update Error 0x800700c1

I have Windows 10 Pro Version 1511, OS Build 10586.589.

Windows continually attempts to download and install the anniversary upgrade.
The download completes, but the installation fails with error code 0x800700c1.
This has happened more than 50 times.
(As appears quite common, I have never experienced an update error before.)

I have tried every suggested fix I can find - nothing works.
I have tried installing from 1607 ISO - fails
I have tried installing using Windows10Upgrade28084.exe - fails
I have tried letting Microsoft Support have a go - fails

I am unable to find the meaning of the error code above, so there seems to be no way to effect action here.
Does anybody have any knowledge on this one?
