Hi, I just finished upgrading one of my servers from Ubuntu 20.04 to 22.04. But my problem now is that unison doesn't run because of incompatibility issue. Here's the version on my server 1: Code: root@server1:~# unison -version unison version 2.48.4 On my server 2 which I upgraded to 22.04: Code: root@server2:~# unison -version unison version 2.51.5 (ocaml 4.13.1) I don't know how to make these servers sync its files now. I don't know how to install unison version 2.51.5 (ocaml 4.13.1) on server 1 either. I can't upgrade server 1 to Ubuntu 22.04 'cause the files in server 2 are not yet updated. Any suggestion is highly appreciated.
You could try installing the same unison version from source on the old server or installing an older version on the new one if you can't find packages for the same version for both systems. Personally, I would always prefer to try upgrading the first system to Ubuntu 22.04 as well.
Never mind. I already solve the problem. What I did is just copy the same version of Unison to /usr/bin/ folder.
