freebsd stable - Aug 2016 - FreeBSD 10.1 can't upgrade to FreeBSD 11-RC1 via freebsd-update

FreeBSD 10.3 works.

FreeBSD 10.1 complains about a failed integrity check etc (which the EN was
supposed to fix, I assume)


I did run freebsd-update to update to the latest patch-level and freebsd-version
said, I was on p37.
