"This is a real show-stopper. It's not possible to fix this with a new protocol version?"
I think the problem is really, why should different versions of a multi- part solution break a system, and the answer is they shouldn't, at least not between minor versions and ideally all versions should be backwards compatible for at least a few major versions. Unison is a great program until you want to run it on different systems, and let's face it, none of us want to build from source if there is a compiled package already available. We don't always have a choice in when different machines are upgraded, even updating might need a server restart that you can't do until the weekend but the desktops are all done the same day. It's a fundamental design flaw. It should be backwardly compatible. Software should ALWAYS be backwardly compatible within minor updates, let alone major ones. -- 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
