Hi,

After updating openstack-tripleo-heat-templates from 10.5 to 10.6 (using centos) and other tripleo packages (minor versions) undercloud fails to upgrade. Ran:

openstack undercloud upgrade

Got as result:

Exception: Post Upgrade failed
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/tripleoclient/v1/tripleo_deploy.py", line 1262, in _standalone_deploy
    raise exceptions.DeploymentError('Post Upgrade failed')

Any ideas on what might be wrong?
