Comment 7 for bug 1485071

@cheryl, after I did a host distupgrade (xenial), synced lxd-images, I no longer have this issue as of this afternoon. "juju deploy charm" works like a charm without needing to do an "add machine". Retested this a couple of times by destroying service and redeploying and also destroying the controller, rebootstrap, redeploy. In all cases it works now.
