Comment 3 for bug 1625667

Notably, there has been no related change of the mirror method since the trusty release. So if it started working later, than that is related to the reworked acquire system.

As such, I'd like this bug to be closed as invalid, as it's not worth it. The pre 1.1 acquire system cannot really deal with failures gracefully.

You could of course try wily, if it works there, you're lucky, and can backport the fix.
