Using a project with LibGit2Sharp built with dotnet publish --configuration Release --runtime linux-x64 --no-self-contained, resulting in libgit2-e632535.so, and running on .NET 6.0.415.

By using strace with some trial-and-error, it seems that LibGit2Sharp requires OpenSSL 1.1, but Ubuntu 22.04 (and higher, I assume) only ship with OpenSSL 3.

As a workaround, installing http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.20_amd64.deb fixes the issue and lets LibGit2Sharp run.

What needs to be done to make this work with OpenSSL 3?

Commencez par la libgit2-e632535.so native produite par le publish linux-x64 et par les emplacements de la trace de pile dans Ensure.cs, Proxy.cs et Repository.cs. Utilisez strace ou une inspection équivalente des dépendances pour confirmer quelles bibliothèques SSL sont demandées sur Ubuntu 22.04. C’est terminé lorsque LibGit2Sharp peut se connecter à un dépôt distant avec les bibliothèques OpenSSL 3 du système, sans installer libssl1.1.
