Comment 3 for bug 1711209

I can reproduce the "nova-manage db sync" error using the latest stable charms:

0) juju-deployer bundle -> http://paste.ubuntu.com/25382733/
1) juju deployer -c bundle.yaml -d -v -s -e my-controller:my-model xenial-mitaka
2) bzr branch lp:openstack-charm-testing
3) source ~/novarc
4) cd openstack-charm-testing
5) ./configure SOME-PROFILE
6) git clone https://github.com/openstack-charmers/openstack-charms-tools
7) cd openstack-charms-tools ; ./os-upgrade.py -o cloud:xenial-newton
8) let hooks finish
9) ./os-upgrade.py -o cloud:xenial-ocata
  - Once this step finishes the nova-cloud-controller is in error state because "nova-manage db online_data_migrations" was not run.

I'll try using the master branch to check if the problem is still there
