先看看主机的网：
shell
ping -c 4 8.8.8.8如果 ping 成功，说明网络连接正常，可以继续排查 DNS 问题。
如果 ping 不通，说明网络有问题，检查网络配置（如虚拟机网络、Docker 网络或代理设置）。
问题通常与 DNS 解析失败有关，手动设置 DNS 服务器： 编辑 /etc/resolv.conf 文件，添加以下内容：
shell
nameserver 8.8.8.8
nameserver 8.8.4.4验证 DNS 是否生效： 尝试 ping 或解析一个域名：
shell
nslookup archive.ubuntu.com
ping archive.ubuntu.com
