[Debug] 踩过的坑-UbuntuDNS配置

Ubuntu18.04重启之后会出现无法连接网络的问题，排查得问题出现在DNS上，然而中文社区对这个方法的解决都不甚令人满意，折腾了半个晚上，才发现This is pretty simple to fix though.

• 若已经连不上网了，先修改/etc/resolv.conf，添加nameserver 114.114.114.114或其他，不要restart network之类的，那样会导致文件被覆盖

• sudo apt install resolvconf

• sudo vi /etc/resolvconf/resolve.conf.d/head

• # Make edits to /etc/**resolvconf**/**resolv**.**conf**.d/head.

  nameserver 8.8.4.4

  nameserver 8.8.8.8.

• sudo service resolvconf restart
