Comment 15 for bug 1563483

Sorry for the late response.

As a test I did a fresh install by doing the following:

apt-get update
apt-get dist-upgrade
add-apt-repository ppa:maas/stable
apt-get install maas

I then created a maas admin user.
I rebooted the server.

After the server rebooted the cluster had become disconnected. I tried this 3 more times and rebooting the server after a fresh install always resulted in the cluster becoming disconnected.
