I have installed maas server and configured juju also, And bootstrapped juju for 1st time, which I know will install zookeeper on 1 "ready" state VM available in MAAS.

So I observed this installation, it installed OS and the rebooted and came to this screen and since then its stuck,

Error command failed: cannot inject a machine without a instance id

errors running cloud_config [final]: [scripts-user]

What are these errors? How can I resolve them?
I am running 12.04.2 LTS, juju version is 1.13.1-precise-amd64 and maas version - 1.3.1

I also checked juju status -v, its gives following message continuously:
