在Debian使用apt-get update出现"E: Some index files failed to download, they have been ignored, or old ones used instead."的错误提示问题

一、替换文件

vim /etc/apt/sources.list 

二、替换文件中的源

deb http://mirrors.aliyun.com/debian wheezy main contrib non-free  
deb-src http://mirrors.aliyun.com/debian wheezy main contrib non-free  
deb http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free  
deb-src http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free  
deb http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free  
deb-src http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free  

这里是替换成阿里云源

三、查看效果

apt-get update
