juju hangs during bootstrapping

Fri Sep 29 14:51:38 UTC 2017

Hi Dave,
May I know which division of Dell you are working on? As i have setup
Openstack deployed t Dell multiple time with MAAS and have not seen this
issue so far.

So please send me log /var/log/cloud-init-output.log which will let us know
what is wrong. Also try sudo apt-get update on the bootstrap node to
confirm you have external access.

In MAAS you can always add the ssh keys to land into the installed nodes
though.

Thanks and Regards,
