无法为 Azure Edge 构建 docker C#，错误 [build-env 6/6] RUN dotnet publish -c Release -o out

Question

我试图在 C# 上构建 Azure Edge 解决方案，但它正在下降，我已经安装了 don't 2.1 Runtime 和 SDK，这是它的输出

dotnet --list-sdks 
2.1.812 [/usr/local/share/dotnet/sdk]

dotnet --list-runtimes                                 
Microsoft.AspNetCore.All 2.1.24 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.1.24 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.1.24 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]

我已经在项目中检查了两个 .sln 或 .csproj 文件

这里是日志：
