1.每次重启需要重新设置
错误提示
正在解析主机 nvidia.app.box.com (nvidia.app.box.com)... 失败：未知的名称或服务。
wget: 无法解析主机地址 “nvidia.app.box.com”
解决方法
通过ctrl+alt+t打开终端
然后gedit /etc/resolv.conf
修改内容为下（将DNS地址改为google域名服务器）
nameserver 8.8.8.8
nameserver 8.8.4.4
最后再次运行就会显示
正在连接 nvidia.app.box.com (nvidia.app.box.com)|8.7.198.45|:443… 已连接。
2.永久有效
解决方法
- sudo apt install resolvconf
- sudo vim /etc/resolvconf/resolv.conf.d/base 在里面插入： nameserver 8.8.8.8
nameserver 8.8.4.4 nameserver 127.0.0.1 - 输入Esc，:wq，保存并退出
- sudo resolvconf -u
- cat /etc/resolv.conf
#Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#DO NOT EDIT THIS FILE BY HAND – YOUR CHANGES WILL BE OVERWRITTEN nameserver 8.8.8.8 nameserver 8.8.4.4 - 在这里，我还要提一点相关内容。虽然我按照方案二并没有达到想要的这种结果(理论上应该是没问题的)，可能是因为我这边配置全局代理，让它默认自动走本地代理路线，所以DNS
Server解析的地址为127.0.0.1，不过至少已经可以使用了，如果方案二行不通的同学，你可以采用方案一，稍微麻烦一点，每次都要进行修改罢了。
最终的结果如下：
