Unable to force Nova version

Unable to force Nova version 14.0.4.

Is there any way to accomplish this using the charm options?

I did not found any way, the default instalation is trough apt and goes to version 14.0.5. I have tried to do it via openstack-origin-git option in the bundle:
...
  openstack-origin-git: |
        repositories:
        - {name: requirements,
          repository: 'git://github.com/openstack/requirements',
          branch: stable/newton}
        - {name: neutron,
          repository: 'git://github.com/openstack/neutron',
          branch: stable/newton}
        - {name: nova,
          repository: 'git://github.com/openstack/nova',
          branch: stable/newton}
        release: 14.0.4
...

Status of the unit: blocked - Services not running that should be: nova-api-ec2, nova-objectstore

In the /var/log/juju/unit-nova-cloud-controller-0.log apparently everithing went well.
