disco and eoan used init scripts whereas the packaging from focal onwards uses systemd units provided directly by the OVN package (the split from OVS happened @ focal).
As a result the issues seen here related to code that is no longer in a supported Ubuntu release (I had to pull from old-releases to confirm this was a problem).
Marking Won't Fix - if you have similar issues with focal or later please open a new bug.
