用你熟悉的编辑器打开：
/etc/apt/sources.list
替换默认的
为
mirrors.aliyun.com
以Ubuntu 14.04.5 LTS为例，最后的效果如下：
deb https://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse deb-src https://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse deb-src https://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse deb-src https://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse deb-src https://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse ## Not recommended # deb https://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse # deb-src https://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
