可以尝试下面四种解决方法:
1、修改Dockerfile文件的基础镜像
将 FROM mcr.microsoft.com/dotnet/aspnet:5.0-buster-slim
改为 FROM mcr.microsoft.com/dotnet/sdk:5.0-alpine
或者
改为 FROM mcr.microsoft.com/dotnet/sdk:5.0-focal
相关文档:https://github.com/NuGet/Announcements/issues/49
2、修改nuget.config配置文件
将下面放在nuget.config中的标签内完全禁用验证(与dotnet restore一起使用)
<config> <add key =“ signatureValidationMode” value =“ accept” />
3、安装ca-certificates软件包
将下面内容添加到Dockerfile文件中:
RUN echo "deb http://deb.debian.org/debian bullseye main" >> /etc/apt/sources.list \ && apt-get update \ && apt-get install -y --no-install-recommends \ ca-certificates \ && rm -rf /var/lib/apt/lists/* \ && sed -i '$ d' /etc/apt/sources.list
4、降级.NET Core的版本
如果上面方法不能解决,可以尝试降级到.NET Core 3.1
