Failure to download IUKv2 from 4.2 to 4.2.1

Initially, I supposed this might be a mirror sync issue, that I was filing anyway since I cannot test 4.2 to 4.2.1 because of that.
But then, looking at b64fcee4, I’m only seeing sha256 fields getting updated.
So this might be a network issue instead. I’ll retry.
