Hi,

I'm new to openstack. I try to install openstack aio like described in https://docs.openstack.org/openstack-ansible/stein/user/aio/quickstart.html (https://docs.openstack.org/openstack-...). Running first two playbooks went ok, but third ( "openstack-ansible setup-openstack.yml" ) break:

TASK [python_venv_build : Install python packages into the venv] *************** FAILED - RETRYING: Install python packages into the venv (5 retries left).

And end up with: ERROR: Could not find a version that satisfies the requirement keystone==15.0.1.dev11 (from -c /openstack/venvs/keystone-19.0.4/constraints.txt (line 125)) (from versions: 12.0.2, 12.0.3, 13.0.2, 14.0.0, 14.0.1, 14.1.0, 15.0.0.0rc1, 15.0.0.0rc2, 15.0.0, 16.0.0.0rc1)\n ERROR: No matching distribution found for keystone==15.0.1.dev11 (from -c /openstack/venvs/keystone-19.0.4/constraints.txt (line 125))\n

It is a single VM install on VirtualBox on Windovs. Guest was CentOS7.6, which was upgraded to CentOS 7.7.

Any help?
