One I just upgraded to 20.04. The other is still at 18.04 LTS. The two unison instances no longer talk happily together. The error is this: Fatal error: Server: Fatal error during unmarshaling (input_value: ill-formed message), possibly because client and server have been compiled with differentversions of the OCaml compiler. which is repeated many times. It seems quite surprising that the issue is really only resolvable as "upgrade all unison instances that might ever talk to each other together or not at all", so I suspect the error message about OCaml build is a red herring. I'm not, however, sure how to debug this, however.
