I confirm Todd Taft's report - this is still an issue in 18.04. The
whole purpose of having Unison as a Debian/Ubuntu package is to provide
the function that Unison is meant for - to allow syncing of files across
not only multiple machines, but multiple versions of an o/s and between
versions of o/s, current and old. This is not the case with Unison on
Ubuntu. It's the death of Unison - eventually - if unison-all does not
include support for unison as installed on heterogenous and old
hardware, other o/s.

Title:
  unison incompatible with older ubuntu/debian versions

Status in unison package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  16.04 comes with a new version of unison, which is great.

  Unfortunately, it comes just with that new version, not older ones.
  Unison can synchronize only with precisely the same version on the
  peer, not interact with others. Therefore a 16.04 machine cannot sync
  to any older linux (ubuntu,debian,...), especially not to servers
  running 14.04.

  Older versions of ubuntu therefore came with different versions of
  unison, i.e. at least the version of the last LTS version to keep it
  functional and to have new clients work with older (but still
  supported) LTS servers.
