The unison in Debian 10 is compiled with OCaml 4.05.0, which is long gone. The only way to synchronize with a buster machine is to use unison from buster. I'm sorry I haven't been sufficiently clear on that. Since the version of OCaml changes at each Debian release, there will not be /in the archive/ a package (or metapackage) that will be compatible with two successive Debian releases (or with stable and testing/unstable). My goal with the new packaging structure is that once a version of Unison is installed, it may be kept installed even after an upgrade of Unison (meta)packages. So, for example, if we transition to a new version of OCaml (say 4.11.0), I will ask for the removal of unison-2.48 from the archive and upload a new unison-2.48+4.11.0. In this hypothetic future, unison-2.48 can be kept installed on systems (or installed from snapshots) where its compatibility set is needed. Moreover, unison-2.48 and unison-2.48+4.11.0 would be co-installable, easing migration from one version to the other. Cheers, -- Stéphane
