ubuntu修复不能解析域名
(apt-get update - No address associated with hostname)
更新 apt 仓库出现以下错误:
W:Failed to fetch http://extras.ubuntu.com/ubuntu/dists/precise/Release.gpg Something wicked happened resolving 'extras.ubuntu.com:http' (-5 - No address associated with hostname)
无论是 wget, dig, ping 都显示是域名解析出了问题。网络也不通,提示unknown hostname,网页也打不开。
以下为修复前的 /etc/network/interfaces:
# interfaces(5) file used by ifup(8) and ifdown(8)
#loopback network interface
auto lo
iface lo inet loopback
# primary network interface
修复域名解析,在 /etc/network/interfaces 加上 dns-nameservers 8.8.8.8
# interfaces(5) file used by ifup(8) and ifdown(8)
#loopback network interface
auto lo
iface lo inet loopback
# primary network interface
auto eth0
iface eth0 inet dhcp
dns-nameservers 8.8.8.8
重启网络服务
# sudo service networking restart
或重启系统,问题被成功修复。
