修改默认下载地址

mv /etc/apt/sources.list /etc/apt/sources.list.bak 

echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >> /etc/apt/sources.list 

echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list 

echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list 

echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list

更新apt-get

apt-get update

这个命令的作用是：同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引，这样才能获取到最新的软件包。

下载vim

apt-get install vim

下载完毕就可以愉快的使用vim了
