As a workaround for me worked this trick with installing libgit2-24 globally and setup its target path in |

I seems I solved the issue by installing That comment helps - #1472 (comment) |

@evil-shrike curl is a requirement, so it sounds like you've fixed the problem! |
|
@bording yeah, but may be it makes sense to put the required curl module besides libgit2-1196807.so? Or at least put some warning in Readme? |
|
Attempting to bundle other libraries instead of linking against the system versions is not something we want to do, especially for something like OpenSSL. Adding something to the README that lists all of the required native dependencies is a good idea! |
We are not going to ship OpenSSL (which we would have to do, transitively), and you don’t want us to. If there are security holes in it, you want a single source of OpenSSL that you can patch. You want to know that you fixed all of them when you do. You don’t want some version that we installed still being vulnerable. |

I agree about openssl, but I think you should statically link libcurl. It is a problematic dependency that various greatly between Ubuntu versions and packages on Ubuntu. I've had more trouble with libcurl than any other library, trying to find the "sweet spot" of configuration for my OS and docker images. |
|
Also, the latest .NET Core 2.1.1 depends upon libcurl4. As it stands, I don't think LibGit2Sharp.NativeBinaries currently work on the latest .NET Core. Try to use it in the latest |

We are currently using the same native library for all versions of Ubuntu. If 18.04 has changed the version of curl it ships, then we'll have to build a specific version of the library for it and ship it in the native binaries package. |
|
This was reproduced on Debian 9 as well, so not just an Ubuntu issue. |
|
The latest 0.26.0 preview release includes both an Ubuntu 18.04 and Debian 9 binary, so it should work. |
|
The following seems to work just fine on Ubuntu 18.10. I've tested with GitVersion modified to use these versions. |

As you can see when I try to remove libssl1.0.0, it's dependents include the .Net Core runtimes and the openssh client. These I have installed. But it also includes the snap daemon, and I belive that was present after the initial OS installation. I've also tried to spin up the |

Thanks for the additional information! That doesn't seem to line up with my initial testing, so it looks like I've got some more investigation to do. However, if we can reasonably assume that |

I got hit with this same problem of libgit2sharp not being able to load the native library (In my case, I had all dependencies needed for the library, but running on Arch Linux instead of Ubuntu. Which is probably not officially supported). I was able to solve this by adding a new I appended the following to the configuration file (without removing anything) <dllmap os="linux" dll="git2-6311e88" target="libgit2.so" />Hopefully this helps someone else coming across this issue with the same problem. |

@maulwuff thanks, that helped me work around the issue (on WSL2 Ubuntu 20.04 .NETCore 3.1.401) |
I have difficulties with LibGit2Sharp while running Cake (with Cake.Git addin) build on Linux Ubuntu 16.04 in Docker - cake-contrib/Cake_Git#68
But I managed to isolate issue with LibGit2Sharp only.
