如何恢复/重新创建/resolv conf文件

no file named resolv.conf in /etc

你可以重新安装resolvconf以恢复默认配置：

sudo apt-get install --reinstall resolvconf

另一个想法是删除"resolvconf"，然后安装：

sudo apt-get remove --purge resolvconf && sudo apt-get install resolvconf

如果resolvconf -u显示/etc/resolv.conf，不是指向/run/resolvconf/resolv.conf的符号链接，那么只需备份resolv.conf，并生成符号链接：

$ cd /etc


$ sudo ln -s /run/resolvconf/resolv.conf
