Hello Felipe, or anyone else affected,

Accepted horizon into artful-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/horizon/3:12.0.2-0ubuntu1.1 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Impact]

  When upgrading from mitaka to pike horizon stops working because
  Apache can't read the static assets anymore

  [Wed Apr 04 11:22:37.470451 2018] [core:error] [pid 17924:tid
  140071592240896] (13)Permission denied: [client 1.2.3.4:60750]
  AH00035: access to /static/dashboard/img/favicon.ico denied
  (filesystem path '/var/lib/openstack-dashboard/static') because search
  permissions are missing on a component of the path

  In xenial the home for the horizon user is /usr/share/openstack-
  dashboard, and /var/lib/openstack-dashboard permissions are changed to
  700 to secure the secret_key, while in artful/pike only the secret_key
  file is set to 700

  # ls -ld /var/lib/openstack-dashboard/
  drwxr-xr-x 4 horizon horizon 4096 Apr 18 18:49 /var/lib/openstack-dashboard/
  # ls -ld /var/lib/openstack-dashboard/secret_key
  -rw------- 1 horizon horizon 64 Apr 18 18:47 /var/lib/openstack-dashboard/secret_key
  # apt-cache policy openstack-dashboard
  openstack-dashboard:
    Installed: 3:12.0.2-0ubuntu1
    Candidate: 3:12.0.2-0ubuntu1
    Version table:
   *** 3:12.0.2-0ubuntu1 500
          500 http://nova.clouds.archive.ubuntu.com/ubuntu artful-updates/main amd64 Packages
          100 /var/lib/dpkg/status
       3:12.0.0-0ubuntu2.1 500
          500 http://nova.clouds.archive.ubuntu.com/ubuntu artful/main amd64 Packages

  So during the upgrade of the package /var/lib/openstack-dashboard is
  left to 700

  xenial -> debian/openstack-dashboard.postinst
  ...
  if [ -d /var/lib/openstack-dashboard ] ; then
  # Generated secret storage for single node use - see local_settings.py
  # for more details of SECRET_KEY
  chmod 0700 /var/lib/openstack-dashboard
  if [ -f /etc/openstack-dashboard/secret_key ]; then
  mv /etc/openstack-dashboard/secret_key /var/lib/openstack-dashboard
  fi
  chown -R horizon:horizon /var/lib/openstack-dashboard
  fi
  ....

  artful -> debian/openstack-dashboard.postinst
  ...
  if ! getent passwd horizon > /dev/null 2>&1 ; then
  adduser --system --home /var/lib/openstack-dashboard --ingroup horizon \
  --no-create-home --shell /bin/false horizon
  fi
  ...

  [Test Case]

  * deploy openstack
    juju deploy ./xenial-mitaka.yaml  # http://paste.ubuntu.com/p/7XtXRvf4cT/

  * upgrade openstack-dashboard to ocata, pike or queens
    juju deploy openstack-dashboard openstack-origin="cloud:xenial-ocata"  # for -proposed use "cloud:xenial-ocata/proposed"

  Expected result:

  http://`juju-deployer -f openstack-dashboard`/horizon/auth/login is
  displayed with all the correct css/js/etc assets

  Actual result:

  http://`juju-deployer -f openstack-dashboard`/horizon/auth/login
  cannot load the static assets (javascript/css/etc)

  [Regression Potential]

  * Users who may have customized /var/lib/openstack-dashboard
  permissions to comply with some specific security policy will see
  changes in the permissions when they upgrade, but this is a common
  situation when packages are upgraded.
