Comment 36 for bug 1755027

This bug was fixed in the package horizon - 3:11.0.4-0ubuntu1~cloud2.3
---------------

 horizon (3:11.0.4-0ubuntu1~cloud2.3) xenial-ocata; urgency=medium
 .
   * d/openstack-dashboard.postinst, d/openstack-dashboard.conf: Align
     with other releases of horizon and use horizon:horizon instead of
     www-data:www-data.
   * d/openstack-dashboard.postinst: Ensure permissions are not
     world-readable for /etc/openstack-dashboard/local_settings.py
     (LP: #1755027).
