解决方案:

 

zcidcs@ubuntu:~$ sudo vi  /etc/resolvconf/resolv.conf.d/base
添加这两行
nameserver 8.8.8.8
nameserver 8.8.4.4

然后

zcidcs@ubuntu:~$ sudo resolvconf -u

再查看下

zcidcs@ubuntu:~$ 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

最后执行

 sudo apt-get update

如果还是错误,就要检查网络配置了。

/etc/network/interfaces

 

OK  解决
