Hi,
with usage types EP and EPBC this role:
pcd:portal_content/administrator/super_admin/super_admin_role
is present on my system. This was either accidentally removed on this system or something went wrong during the installation. There is no way to recreate this role in the DB.
If you are not able to carry out the required admin tasks using the content_admin_role you need to reinstall the system from scratch.
Kind regards,
Jozsef
