maas 2.7 stuck at Waiting for rack controller(s) to sync

Fresh install of MAAS 2.7. I enabled centos 7 under images. I saw it download and it flashed something like ‘syncing to rack controller’ but now ubuntu 18.04 and centos 7 are both stuck at ‘Waiting for rack controller(s) to sync’ and I can’t even add a machine … something about a missing ephemeral image.

This feels DOA to me.

updated https://bugs.launchpad.net/maas/+bug/1836936 with my details even though it appears that this bug has been removed from the 2.7 release train :frowning:
