Title:
  (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

Status in horizon package in Ubuntu:
  Confirmed

Bug description:
  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
  ...
