Can't run on Ubuntu 20.10

[cszczepaniak]

I get the error below when running on Ubuntu 20.10. I did a bit of research on this and it appears that LibGit2Sharp just doesn't support this version on Linux. Is there any way around this, or a way to make cross platform support more robust?

Unhandled exception. System.TypeInitializationException: The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an exception.

After a bit more research, it may be possible to also include a reference to LibGit2Sharp.NativeBinaries: https://stackoverflow.com/questions/35028958/not-able-to-run-libgit2sharp-on-mono-on-ubuntu

I can confirm the problem, it also happens on Ubuntu 20.04.

this exact problem also happens on M1 Mac unter macOS "Monterey".

I can reproduce this; it seems the root cause is that LibGitSharp2 doesn't support Ubuntu 20.x yet. It seems they fixed this (libgit2/libgit2sharp#1747) but even latest preview didn't fix this yet. I'll need to take a closer look again.

FWIW I was able to make this work by creating a properly versioned directory under runtimes directory and copying the .so there.
It was some time ago and I doubt I have the VM still.

Overall yes, using raw git would be better

this error is throwing on Ubuntu 22.04.2 LTS. is there any solution or patch?
