@christos pontikis (pontikis) this saved my day, thanks!

As a small improvement: you do not need to remove all cache, just the
fp* files that have been created after you started using the new
version.

I think that this is the kind of software that would benefit greatly the
snap/appimage/flatpack whatever, to have always the same version in all
your machines...

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.
