For the rest is there no reference to either the packages python-neutron-fwaas or python-neutron-vpnaas.
On the cloud the other 2 unit's upgraded fine, the resulting package versions of all three units are; https://pastebin.canonical.com/p/fbHfdsDGHY/
Due to the fact that python-neutron-fwaas & python-neutron-vpnaas where not upgrade the service was unable to start. The fix was: "sudo apt install python-neutron-fwaas python-neutron-vpnaas" which worked without a problem and / or a prompt for help packages etc, and resolved the non-working unit
