Updating a node fails with invalid OS and distro series

[Andreas Hasenack]

maas 1.7.5+bzr3369-0ubuntu1~trusty1

I can't seem to edit and save changes to an existing node.

Via the API:
$ maas admin-atlas node update node-1440bcfa-1b7e-11e5-846c-2c59e54ace74 hostname=lapras
{"osystem": ["Select a valid choice. ubuntu is not one of the available choices."], "distro_series": ["Select a valid choice. ubuntu/trusty is not one of the available choices."]}

Interestingly, of all the nodes I have, this is the only one that has the fields "osystem" and "distro_series" already filled in.

In the UI, the error is the same (screenshot attached). All other nodes are OK. Images are imported. Cluster is in sync.

Update: the node update call worked after I started the node up.
