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:

python-ceph is not getting install due to dependencies:
#vi /etc/ansible/roles/ceph_client/vars/debian.yml.
python_ceph_packages:
- python-ceph
- python3-rados
- python3-rbd
I tried to update python-ceph with python3-ceph and the deployment was successful but the cinder-volume service is not coming up due to python error:
