我已经按照此处所述的方式设置了我的 docker。 守护进程的错误响应：获取 \'https://registry-1.docker.io/v2/\'：proxyconnect tcp：dial tcp：lookup proxy.example.com on 8.8.8.8:53：没有这样的主机
但是目前执行 sudo apt upgrade 之后，我面临的问题是即使在拉取之后也无法运行大多数 docker 镜像。

我该如何修复它？
docker run ubuntu:22.04 什么都不做。它启动一个 shell，发现没有 TTY 连接并终止。所以这是意料之中的。如果你添加该 -it 选项，它会以交互方式运行它，如下所示：
docker run -it ubuntu:22.04
然后你应该进入容器中的 shell。一旦你退出 shell，容器就会终止。这就是容器的工作方式。它们只在内部进程运行时运行。
的原因 docker ps 是它只显示正在运行的容器，而你没有任何容器。如果你有
docker ps -a
它还将显示已终止的容器，您应该会看到您的 Ubuntu 容器处于退出状态。
