Comment 28 for bug 1665459

Hi all,

I am experiencing exactly the same issue with my installation.

It is:

Ubuntu 16.04.2 LTS

ii maas 2.1.3+bzr5573-0ubuntu1~16.04.1 all "Metal as a Service" is a physical cloud and IPAM
ii maas-cli 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS client and command-line interface
ii maas-common 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS server common files
ii maas-dhcp 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS DHCP server
ii maas-dns 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS DNS server
ii maas-proxy 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS Caching Proxy
ii maas-rack-controller 2.1.3+bzr5573-0ubuntu1~16.04.1 all Rack Controller for MAAS
ii maas-region-api 2.1.3+bzr5573-0ubuntu1~16.04.1 all Region controller API service for MAAS
ii maas-region-controller 2.1.3+bzr5573-0ubuntu1~16.04.1 all Region Controller for MAAS
ii python3-django-maas 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS server Django web framework (Python 3)
ii python3-maas-client 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS python API client (Python 3)
ii python3-maas-provisioningserver 2.1.3+bzr5573-0ubuntu1~16.04.1 all MAAS server provisioning libraries (Python 3)

I've implemented Blake's suggestion:

Edit /etc/maas/rackd.conf and change maas_url:

maas_url=http://{ip_rack_and_machines_can_reach}/MAAS

Restart the maas-rackd service:

sudo systemctl restart maas-rackd

and applied a patch recommended by Mike:

         subnets = self.raw(

The issue is still there.

I am very interested making the system work and hope it can be fixed soon.

Thanks a lot,
