我使用的是Ubuntu 18.04，您能告诉我如何解决吗？

Answer 1

从提供的日志来看，该问题似乎是网络问题：

 network error (check Internet connection and firewall)

可能的根本原因：

您的机器无法访问互联网
您正在使用代理访问互联网
您的防火墙不允许访问

Answer 2

无法从docker容器访问外部Web。除了我自己的域和某些GoDaddy特定的IP地址之外，我无法从Docker容器访问任何外部IP地址。

如果我尝试ping谷歌dns，那必须可以ping，我得到以下响应：

PING 8.8.8.8 (8.8.8.8): 56 data bytes

--- 8.8.8.8 ping statistics ---
1 packets transmitted, 0 packets received, 100% packet loss```

docker-compose build nginx：网络错误（检查Internet连接和防火墙）
