    $ sudo vi /etc/resolv.conf

     修改为114.114.114.114

    添加:

    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

    重启网络:

    sudo /etc/init.d/networking restart

     

    再执行命令:sudo apt-get update

    执行完成,然后:

    sudo apt-get upgrade
