This may help. After upgrading my Desktop from Mint19 to Mint20 I could not get unison file sync working to my Ubuntu Server. With some help from the guys on the GitHub issues list I have now fixed it. Apparently unison for Ubuntu19 and Mint20 are compiled differently, and even though they are both version 2.48.4 they are compiled with different releases of OCaml, which makes them incompatible. This is what I did - Remove all traces of unison then run wget http://mirrors.kernel.org/ubuntu/pool/universe/u/unison/unison_2.48.4-1ubuntu1_amd64.deb wget http://mirrors.kernel.org/ubuntu/pool/universe/u/unison/unison-gtk_2.48.4-1ubuntu1_amd64.deb sudo dpkg -r unison this removes the old install sudo dpkg -i unison_2.48.4-1ubuntu1_amd64.deb sudo dpkg -i unison-gtk_2.48.4-1ubuntu1_amd64.deb sudo apt-mark hold unison this stops it updating sudo apt-mark hold unison-gtk
This is not a proper solution it is just a fix, but it did get me out of a hole :) Mick -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1568459 Title: unison incompatible with older ubuntu/debian versions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unison/+bug/1568459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
