Upstream provides binary builds for many different platforms!  Here:
https://github.com/bcpierce00/unison/releases

Currently the latest Unison there is 2.52.1, and the latest OCaml
compiler is 4.14.0, so I installed
"unison-v2.52.1+ocaml-4.14.0+x86_64.linux.tar.gz" (2022-05-08) into
/usr/local/bin/ on both my Ubuntu 20.04.5 (focal) and 22.04.1 (jammy)
machines.  That works!

So, since the Unison author provides binary builds that seem to work
everywhere, shouldn't the Ubuntu packaging problem reduce to simply
providing those exact same binaries for EACH version of Ubuntu, either
in its main repository or in backports?

Title:
  Unison incompatible between ubuntu 20.04 and 22.04

Status in unison package in Ubuntu:
  Confirmed

Bug description:
  The same problem as every other year:

  With every new LTS release unison becomes incompatible with the new
  and the last Ubuntu release. Even if not incompatible in a technical
  way, unison compares the version string and denies to communicate with
  a different version.

  So it is (without dirty workarounds such as running an old unison in a
  docker image) not possible to synchronize files between a 20.04 and a
  22.04 machine.

  
  Would be nice, to either have the old version available in 22.04, or the new version available in 20.04. 

  regards
