配置方法

1.打开设置

cd /etc/apt/
cp sources.list  sources.list.bak
vi  /etc/apt/sources.list

2.打开后粘贴最新镜像源

比如，阿里云的镜像，最新版：

阿里巴巴开源镜像站-OPSX镜像站-阿里云开发者社区

选择自己的 Ubuntu 版本，复制下面的代码到 sources.list

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 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
