Comment 0 for bug 1773117

Just performed a bootstrap to a KVMs on MAAS v2.3.3
added a new model "deployment"
installed postgresql-HA
then returned to controller model and enable-ha I got this many times:

machine-0: 10:46:03 ERROR juju.worker.dependency "machiner" manifold worker returned unexpected error: cannot update observed network config: cannot get network interfaces of "4s33ky": instance "4s33ky" not found (not found)
