vagrant example cluster are failing to deploy

[agowa]

I tried to spin up a new single-node cluster but it fails prematurely within the cloudinit unit with the error:

I followed the instructions at: https://coreos.com/kubernetes/docs/1.6.1/kubernetes-on-vagrant-single.html

And also the multi-node seam to have the same problem:
