该项目是在 Mono 下开发的，依赖于一些 nuget 包。我使用 Gitlab CI 来运行构建。构建环境是docker ubuntu。所有其他 apt-get 安装工作正常，但无论我如何修改参数和 NuGet.config，nuget 都不会恢复包。我在 v2 和 v3 之间切换，并尝试了我在互联网上可以找到的所有内容:

http://docs.myget.org/docs/how-to/package-not-found-during-package-restore

但仍然出现以下错误:

在我的本地机器上，我可以使用完全相同的命令从在线源成功恢复所有包。

最佳答案

根据您使用的 Ubuntu 版本，将 ca-certificates-mono 添加到您的环境中可能会有所帮助:

apt-get install -y --allow-unauthenticated ca-certificates-mono

我将 Docker 与 Stretch 和 this thread 结合使用修复了我与你的相同的问题。
