@cmarquardt we can reproduce the same. Is there a fix coming for this?

[cmarquardt]

To be honest, probably not. I never managed to find out in detail what is causing the problem and how to fix it.

In my case, binaries produced on one version of a Linux distribution/system run fine on that OS version but fail on some (not all) other versions or distributions. I remember that loading some shared library failed upon startup (OpenSSL, I believe due to a version mismatch). I guess that I would need to include these libs in the executable built by PyInstaller somehow. But my knowledge of and experience with PyInstaller is minimal. In practice, I ended up rebuilding the binaries on a machine running the target OS and then distributing the binaries to other boxes with the same version of Linux.

But if you know how to fix it, I'd be grateful - and a pull request would be even better;-)

Thank you for your answer! Unfortunately my python skills are down to a bare minimum. I need to run this on an old Ubuntu 14.04 and can not (because of dependencies) update the OS or even python.

Thats why I wanted to try your pre-compiled binary. Do you think it is safe using it then? I can dispense the use of --version if the rest is still working.

Thanks in advance

I'm not familiar with PyInstaller, but this looks to be a similar issue (including a possible solution): https://github.com/pyinstaller/pyinstaller/issues/1713

One potential difference is that borgmatic --version in particular relies on pkg_resources to pull in borgmatic's package metadata:

   if global_arguments.version:
        print(pkg_resources.require('borgmatic')[0].version)
        sys.exit(0)

So if that package metadata is not fetchable with PyInstaller, then that approach of course won't work.

I'm open to other ways of determining the borgmatic version at runtime if it leads to better results with PyInstaller.
