The author primary signature's timestamp found a chain building issue: UntrustedRoot: self signed certificate in certificate chain

今天打包编译的时候出现错误"The author primary signature's timestamp found a chain building issue: UntrustedRoot: self signed certificate in certificate chain"

其原因是debian的dotnet sdk镜像证书链出现问题, 

github针对此问题的讨论issue: NuGet restore failing on .NET 5 for Debian-based OSes (CA trust changed) · Issue #10491 · NuGet/Home (github.com)

我的解决办法: 

按照 dsaul的说明， https://github.com/NuGet/Home/issues/10491#issuecomment-768687027

我打包了新的sdk镜像: https://hub.docker.com/repository/docker/agilelabsnet/dotnet-sdk

docker push agilelabsnet/dotnet-sdk:5.0

Dockerfile: https://github.com/DukeCheng/dotnet-docker-cst/blob/main/5.0/sdk/buster-slim/amd64/Dockerfile
