不能build立官方的asp.net泊坞窗图像

我无法在Windows 10 PC上构build官方的ASP.net docker镜像： microsoft / aspnet – Docker Hub

我正在使用4.6.2版本的dockerfile，并且在执行命令时出现错误：

#download Roslyn nupkg and ngen the compiler binaries RUN Invoke-WebRequest https://api.nuget.org/packages/microsoft.net.compilers.2.3.1.nupkg -OutFile c:\microsoft.net.compilers.2.3.1.zip ; \ Expand-Archive -Path c:\microsoft.net.compilers.2.3.1.zip -DestinationPath c:\RoslynCompilers ; \ Remove-Item c:\microsoft.net.compilers.2.3.1.zip -Force ; \ &C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe install c:\RoslynCompilers\tools\csc.exe /ExeConfig:c:\RoslynCompilers\tools\csc.exe | \ &C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe install c:\RoslynCompilers\tools\vbc.exe /ExeConfig:c:\RoslynCompilers\tools\vbc.exe | \ &C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe install c:\RoslynCompilers\tools\VBCSCompiler.exe /ExeConfig:c:\RoslynCompilers\tools\VBCSCompiler.exe | \ &C:\Windows\Microsoft.NET\Framework\v4.0.30319\ngen.exe install c:\RoslynCompilers\tools\csc.exe /ExeConfig:c:\RoslynCompilers\tools\csc.exe | \ &C:\Windows\Microsoft.NET\Framework\v4.0.30319\ngen.exe install c:\RoslynCompilers\tools\vbc.exe /ExeConfig:c:\RoslynCompilers\tools\vbc.exe | \ &C:\Windows\Microsoft.NET\Framework\v4.0.30319\ngen.exe install c:\RoslynCompilers\tools\VBCSCompiler.exe /ExeConfig:c:\RoslynCompilers\tools\VBCSCompiler.exe ; 

执行ngen.exe时发生错误，似乎是数字签名失败的一个王者：
