Currently, LibGit2Sharp doesn’t work/support Ubuntu 18.04. There is an open PR for it though:

libgit2/libgit2sharp.nativebinaries#74

[LordMike]

@gep13 the PR mentioned has now merged.

[dazinator]

I think this is waiting on pr #1422 to be merged, If you want to test it sooner you could try a build of that PR.

[mikesigs]

It looks like the fix for this is included in LibGit2Sharp v0.26.0. Can we pretty please get this updated in GitVersion v4? We are using AWS CodeBuild and it uses Ubuntu 18.04 and we're completely dead in the water because of this silly libcurl4 issue.

Thanks!

https://github.com/libgit2/libgit2sharp/blob/a709ab84d4/CHANGES.md#v026---diff

The underlying native library (libgit2) now no longer relies on libcurl

[GeorgDangl]

Is there any update on this issue?

[PashCracken]

Any progress on this? Would really like to see it fixed

[dazinator]

Have you tried the 5.0.0 beta release? https://www.nuget.org/packages/GitVersion.CommandLine.DotNetCore/5.0.0-beta3-4

There is also a dotnet cli global tool now you might be interested in: https://www.nuget.org/packages/GitVersion.Tool/5.0.0-beta3-4

[PashCracken]

I tried to use the latest 5.0.0 beta global tool on Ubuntu 18.04. It still fails with the same error

[GeorgDangl]

I’m actually using the beta release. Both beta3-4 and the latest one (3-27 I think) have this issue. As far as I understand it, it requires an update of the LibGit2 dependency to be resolved.

I can’t really use another GitVersion approach, e.g. the dotnet tool, since I’m just consuming it via the NUKE build project (cc FYI @matkoch)

My CI workaround is to serialize the GitVersion Information in a Windows node and then use that on a Linux node.

[mikesigs]

If docker is an option for you, that was the best solution we found to overcome this problem.
There is an "official" image out there for running GitVersion inside a container, where it has all the requirements it needs built in. gittools/gitversion-dotnetcore

Here's an example usage:

GITVERSION_INFO=$(docker run --rm -v "$(pwd):/repo" gittools/gitversion-dotnetcore:linux-4.0.0 /repo)
export INFORMATIONAL_VERSION=$(echo $GITVERSION_INFO | jq -r .InformationalVersion)

@JeremyCade, as LibGit2Sharp was upgraded to version 0.26 in #1713, we hope this problem should be gone now. Can you please try [the latest buildhttps://www.nuget.org/packages/GitVersionCore/5.0.0-beta4-1) and let us know how that works for you? Please reopen if you still have issues.
