我想安装 git。但是会发出此错误。

在此之前，java和maven都是正常安装的。

可能是什么问题呢？

执行“apt-get update”命令时，我遇到了类似的错误。

您的 docker 引擎中可能存在 DNS 问题。

您可以通过运行来测试理论:

docker run busybox ping archive.ubuntu.com

看看它是否解决。

然后，做同样的事情，但允许主机网络或明确提供 DNS:

docker run --network host busybox ping archive.ubuntu.com
docker run --dns 8.8.8.8 busybox ping archive.ubuntu.com

要获得永久解决方案，您可能需要编辑 /etc/docker/daemon.json并重新启动 docker 引擎:

{
    "dns": ["192.10.0.2", "8.8.8.8"]
}
