.NET 5.0 Docker 镜像 错误修复方法

在给​​eshopondapr​​ 打镜像的时候碰到了3个错误

1、restore: Received an unexpected EOF or 0 bytes from the transport stream： ​​https://github.com/NuGet/Home/issues/9020​​

2、Notice: NuGet Restore Failures on Linux distributions using NSS or ca-certificates #10712 :​​https://github.com/NuGet/Home/issues/10712​​ 

3、In .NET Core, libMan install 'Failed to download resource' #476：​​https://github.com/aspnet/LibraryManager/issues/476​​ 

解决方法：

1、.NET SDK 更新到​​5.0.202+​​​ 或 ​​升级​​​ ​​.NET 6 Preview 3+​​​  ： ​​https://devblogs.microsoft.com/nuget/net-5-nuget-restore-failures-on-linux-distributions-using-nss-or-ca-certificates/ ​​

2、添加 --disable-parallel选项： RUN dotnet restore "eShopOnDapr.sln" --disable-parallel

3、运行命令 dotnet tool update --global Microsoft.Web.LibraryManager.Cli
