For reference this is with MAAS from raring.

From digging into the code, it looks like we implemented MaasProvider.Instance.Addresses by reading the "ip_addresses" field from the node listing.

But that was added in rev 1521 of MaaS which *isn't* in Raring.

It didn't matter before because we only used DNSName which uses the "hostname" field of the node list.

My suggestion is to try ip_addresses and if the request fails, fall back to hostname

Was this supposed to be fixed in 1.16.0? I just tested it and it is not. Still getting the error:

Can anyone please comment on this? This is NOT fixed in 1.16 as noted above. I've tested this.

Kurt, can you attach a full log? That message shouldn't be possible with 1.16, and I've had other reports that the bug is indeed resolved. Did you upgrade an existing juju deployment, or start from scratch with the new version? Can you double check that the binaries getting run are the new ones? Thanks!

Thank you Martin. After syncing tools and running juju-upgrade, I've validated this is fixed. Sorry for the confusion.
