Mac docker构建镜像apt-get update报GPG签名错误解决

我正在使用python37作为基础镜像制作项目镜像,但构建过程中执行apt-get update时出现GPG签名错误

本地操作系统为Mac OS,docker 环境为desktop for docker :

Docker version 20.10.7, build f0df350

错误详情:

Err:1 http://ports.ubuntu.com/ubuntu-ports focal InRelease
  At least one invalid signature was encountered.
Get:4 http://ports.ubuntu.com/ubuntu-ports focal-security InRelease [107 kB]

解决方案:

docker image prune -a

会清理一些镜像,然后再进行构建,就没有报错了
