Comment 3 for bug 1666069

We track Juju 2.x bugs in "juju" project. I'll re-target :)

I guess that when you say "..if I need to deploy something that needs a Trusty machine...everything is pending forever..." what you are actually observing is that command "juju deploy" returns fine but the provisioning of machines is "pending".

Provisioning of machines is happening asynchronously by a worker. So there would not be anything useful returned from "deploy" command itself.

We have improved "juju status" values and changes in Juju 2.1 and your experience should be better with newer version. I will double check whether we specifically surface image related error in status.

Meanwhile the best practice to diagnose why a machine is in "pending" is by examining its log. Controller and model logs would have information about whether the image was found on or not.
