It appears the ``neutron-common`` package is missing the
'/etc/neuton/rootwrap.d/netns-cleanup.filters' file [0].
On Focal, once the filter is in place the command will still fail due to
the net-tools package not being installed (for netstat). Perhaps we need
a dependency or at least a soft-dependency on net-tools for
``python3-neutron``?
