Satellite 6 installer fails with the following error - "No Puppet module parser is installed and no cache of the file /usr/share/foreman-installer/modules/certs/manifests/init.pp is available."

Issue

• Why does the execution of a satellite-installer command on a freshly installed Satellite Server fails with the following error -

  # satellite-installer --scenario satellite --foreman-initial-organization "Example_Org_Name" --foreman-initial-location "Example_Location_Name" --foreman-initial-admin-username admin --foreman-initial-admin-password 'xxxxxxxxxxxxxxxx'
