"Couldn't resolve host" This is a problem with either your dns or your internet connection.

“无法解析主机”这是您的dns或internet连接的问题。

To test your internet connection you can test that you receive answers from the ping: ping 8.8.8.8

要测试您的internet连接，您可以测试您从ping: ping 8.8.8.8中收到答案。

To test your dns you can test that with: ping www.google.com

要测试你的dns，你可以用:ping www.google.com来测试。

If its an internet connection problem you can check that you have a valid gateway with: ip route show

如果它是一个网络连接问题，您可以检查您有一个有效的网关与:ip路由显示。

If its a dns problem, check in your /etc/resolv.conf that there are valid entries like: nameserver 8.8.8.8 nameserver 8.8.4.4

如果是dns问题，请检查您的/etc/resolv。如果有有效的条目，比如:nameserver 8.8.8.8 nameserver 8.8.4.4。

#2

I had the same problem with DNS entries disappearing being the problem...

我遇到了同样的问题，DNS条目消失了……

try #curl http://www.google.com and see if the system throws up an empty resolv.conf file...

试试#curl http://www.google.com，看看系统是否弹出一个空的resolv。配置文件…

if so,

如果是这样,

vi /etc/resolv.conf

enter... nameserver 8.8.8.8 nameserver 8.8.4.4

输入……命名服务器8.8.8.8命名服务器8.8.4.4

or use your isp's nameservers

或者使用isp的域名服务器。
