cloud-init was recently updated to 19.2-36-g059d049c-0ubuntu1~18.04.1 this update has broken bond and bridge configuration in MAAS. static and DHCP configuration do not seem to be effected. Machines configured with bonds and bridges will sometimes be able to contact MAAS to finalize the deployment however I have been unable to connect to any machine post deployment.
