Unable to determine purpose for node: node-08.maas when deploying multiple OS's

[Andres Rodriguez]

I was trying to deploy various OS at the same time, and the following error appeared:

This issue is because of how operating systems that can have license keys is used. The ending '*' on the release value needs to be strip to set the correct distro_series.
