I'm using Redhat 7.3, RDO ocata. I've been following the install guide (https://docs.openstack.org/project-install-guide/container-infrastructure-management/ocata/install-rdo.html (https://docs.openstack.org/project-in...)).

When I run su -s /bin/sh -c "magnum-db-manage version" magnum I get the following error:

su -s /bin/sh -c "magnum-db-manage version" magnum
