Comment 2 for bug 1577863

I don't think this is a dup of 1573046. It's actually very recreatable post install or post upgrade.

I have attached the screenshot to show symptom when this happens. I recreated with both 1.9.2 and 2.0. For that scenario, it uses Xenial even though Trusty and no minimal kernel is selected.

I was actually able to clear it by selecting the hwe-x kernel in the list and Clicking on save. The save operation cleared the list and dropdown came back with no minimal servers selected and a list of available kernel that did not include hwe-x. At that point, I was able to commission the servers (with trusty ephemeral image).
