Dear Team, I am trying to deploy an openstack-ansible train with Ceph-ansible. I am stuck in a loophole due to python dependencies. As suggested, I applied a fix for the rabbitmq version and I am able to deploy openstack-ansible train successfully without ceph. But when I am deploying it with ceph then it is getting stuck at below: TASK [ceph_client : Install ceph packages] ********************************************************************************************************************************* FAILED - RETRYING: Install ceph packages (5 retries left).
