comments https://bugs.launchpad.net/charm-keystone/+bug/1827668/comments/10 and https://bugs.launchpad.net/charm-keystone/+bug/1827668/comments/9 are unrelated to this bug. That was due to [1] which broken mojo as the relative 'tests/' directory did not exist to put the keystone_juju_ca_cert.crt file in.
