Cloud is configured for Bionic-Ussuri, using "cloud:bionic-ussuri" as their openstack-origin.

All of the openstack-dashboard units in this deployment failed during their install hook due to unmet dependencies on the python3-django-horizon package:

Can reproduce locally, our (OpenStack charmers) bionic-ussuri gate is as well broken. python3-django-horizon depends on python3-swiftclient >= 1:3.9.0-0ubuntu1.1~ but a version satisfying this constraint is only available in Ubuntu Cloud Archive `ussuri-proposed` but not `ussuri` yet:

$ cmadison python3-swiftclient | grep ussuri
 python3-swiftclient | 1:3.9.0-0ubuntu1~cloud0 | ussuri | bionic-updates | all
 python3-swiftclient | 1:3.9.0-0ubuntu1.2~cloud0 | ussuri-proposed | bionic-proposed | all

[Corey Bryant (corey.bryant)]

This should be fixed shortly. The python-swiftclient is on it's way to ussuri-updates.

The charm can now be deployed again on bionic-ussuri: http://osci:8080/job/test_charm_func_full/10728/console
