Public bug reported: The same problem as every other year:
With every new LTS release unison becomes incompatible with the new and the last Ubuntu release. Even if not incompatible in a technical way, unison compares the version string and denies to communicate with a different version. So it is (without dirty workarounds such as running an old unison in a docker image) not possible to synchronize files between a 20.04 and a 22.04 machine. Would be nice, to either have the old version available in 22.04, or the new version available in 20.04. regards ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: unison 2.48.4-4ubuntu1 ProcVersionSignature: Ubuntu 5.4.0-109.123-generic 5.4.178 Uname: Linux 5.4.0-109-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu27.23 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: LXQt Date: Sat Apr 30 13:06:45 2022 InstallationDate: Installed on 2020-06-12 (686 days ago) InstallationMedia: Lubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) SourcePackage: unison UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: unison (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971036 Title: Unison incompatible between ubuntu 20.04 and 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unison/+bug/1971036/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
