All errors appear to be on the neutron gateway.

Title:
  neutron 2:14.0.3-0ubuntu1~cloud0 and 2:14.0.0-0ubuntu1.1~cloud0 not
  compatible

Status in neutron package in Ubuntu:
  New

Bug description:
  Hi,

  Not entirely sure why, but if a cloud has services running these 2
  versions of neutron (2:14.0.3-0ubuntu1~cloud0 and
  2:14.0.0-0ubuntu1.1~cloud0), networking is basically broken until
  everything is running 2:14.0.3-0ubuntu1~cloud0.

  Which causes networking disruption when not all nodes are upgraded at
  the same time.

  Thanks
