Same here. Upgraded client to Focal, server is Bionic. Same version numbers of unison, but the cryptic, misspelled message about incompatible ocaml versions appears.
It would be nice to get this fixed, or at least hints about how to work around the problem... -- You received this bug notification because you are a member of Debian OCaml Maintainers, which is subscribed to unison in Ubuntu. https://bugs.launchpad.net/bugs/1868502 Title: Synchronization with earlier Ubuntu versions or a recent Debian version fails Status in unison package in Ubuntu: Confirmed Bug description: Any synchronization I want to do with my server (Debian buster) fails with the following message: > 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. Indeed, buster uses OCaml 4.05.0, focal uses 4.08.1. eoan used 4.05.0, as did the prior versions, including bionic, which all still synchronize fine. The current Windows version also synchronizes with that version. Although intentionally using an old software version for compatibility is not a good thing, in this case it might be necessary. The whole point of unison is its interoperability.
