Comment 0 for bug 1634475

After the package is installed some of the files that support the initialisation of the database seem to missing. As does the policy.json.

The files that are missing:

/usr/lib/python2.7/dist-packages/mistral/actions/openstack/mapping.json
/usr/lib/python2.7/dist-packages/mistral/resources (directory + contents)
/etc/mistral/policy.json

Without the DB files the schema initialisation fails:
# mistral-db-manage --config-file /etc/mistral/mistral.conf populate
Traceback (most recent call last):
  File "/usr/bin/mistral-db-manage", line 10, in <module>
    sys.exit(main())

    MAPPING_PATH)).read())
IOError: [Errno 2] No such file or directory: '/usr/lib/python2.7/dist-packages/mistral/actions/openstack/mapping.json'

And without the policy.json clients cannot authorise.

Reproduce db issue:
lxc launch ubuntu-daily:yakkety
lxc exec <container-name> bash
apt update
apt install mistral-api
mistral-db-manage --config-file /etc/mistral/mistral.conf populate
