  Test completeness and readiness of OpenVAS-9
  (add '--v6' or '--v7' or '--v8'
   if you want to check for another OpenVAS version)

  Please report us any non-detected problems and
  help us to improve this check routine:
  http://lists.wald.intevation.org/mailman/listinfo/openvas-discuss

  Send us the log-file (/tmp/openvas-check-setup.log) to help analyze the problem.

  Use the parameter --server to skip checks for client tools
  like GSD and OpenVAS-CLI.

Step 1: Checking OpenVAS Scanner ...
        OK: OpenVAS Scanner is present in version 5.1.3.
        OK: redis-server is present in version v=5.0.7.
        OK: scanner (kb_location setting) is configured properly using the redis-server socket: /var/run/redis-openvas/redis-server.sock
        OK: redis-server is running and listening on socket: /var/run/redis-openvas/redis-server.sock.
        OK: redis-server configuration is OK and redis-server is running.
        ERROR: The NVT collection is very small.
        FIX: Run a synchronization script like greenbone-nvt-sync.

 ERROR: Your OpenVAS-9 installation is not yet complete!

Please follow the instructions marked with FIX above and run this
script again.
