Cannot build kernel snap

[MikeB]

This was buried in another thread, but I wanted to give it its own thread
since this has me blocked.

As of late last week, I've been unable to build a kernel snap.

I'm using the latest snapcraft and snapd (2.16 and 2.14.2~16.04
respectively).

I do define an x-kernel plugin which derives from he kernel plugin.  My
x-kernel applies patches after the super().pull() and pauses the process
after the super().build() so that I can inject some custom drivers into
/lib/modules/...  so I don't suspect my x-kernel is the culprit.

When snapcraft tries tries to download ubuntu-core, I get the following
failure.

Any thoughts on how to get around this failure?

Regards, Mike
