Hi Dave,

It looks like we might have had some trouble with the AWS Lambda functions that support the AWS instances (thanks for your detailed report!), and we're looking into that.  This investigation is frustrated by the fact that it appears to be working now -- but that should work in your favor.  Please will you try once more and see if it works for you?

The Ansible setup should work for the local build as well. Since this is building a virtual machine, it can be problematic doing it from a virtual machine.  (The same is true for running it on an AWS instance.)  Are you able to get your hands on an Ubuntu host machine?

I see also we're a few versions behind in the releases of the build-your-own; we'll update that.
