.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
