您缓存了一个过时的更新，因此apt正在尝试从存储库中不再存在的版本安装这些软件包。这就是为什么不提及这些步骤：
FROM php:8.0-apache
RUN apt-get update \
&& apt-get install wget unzip zip -y
从您现在看到的第二个问题来看，您的容器中存在一个网络问题。有很多可能的原因，包括主机未连接到网络，以及docker引擎启动后网络发生变化。您需要提供更多的调试（您可以从主机访问这些节点、DNS是否工作、网络上是否有代理或防火墙等）。请分享更多详细信息。这与编程有什么关系？您试图解决什么问题？谢谢您的回答，但它不起作用。我更新了编辑部分下的输出。
