Can you install from testing (buster) on these systems? I.e. download the .deb file from the net and install using dpkg directly. There is only a dependency on libc6 (>= 2.17); maybe that's satisfied on those systems? Maybe not, of course... The ocaml aspect hit me recently in that unison v2.48.3 and v2.48.4 are incompatible with each other. A real mess. Finally managed to get all my systems running v2.48.4... unison is a fantastic tool but these incompatibilities make it incredibly frustrating to use every now and again. You could consider the following options: 1. build unison yourself on each system from source. 2. try other tools such as syncthing. Hope you get this sorted! -- Eric S Fraga via Emacs 27.0.50, org 9.1.4
