运维系列&Ubuntu（亲测有效）：apt update时：解决Some index files failed to download.They have been ignored, or old apt update时：解决Some index files failed to download.They have been ignored, or old ones used instead报错阅读详情

今天开发部门给我反映apt-get update的时候报404错误，并且apt-get install xxx 不能安装软件，鼓捣了俩小时，最后临时解决了，先说临时解决办法：

sudo vim /etc/apt/sources.list (要注意，有的系统里面是source.list，ubuntu 17.04是souces.list，多了个s)

(遇到这个问题脑海里第一时间想到的是源的问题，换ubuntu源后问题依旧，最后死马当活马医，换debian的源)

将sources.list清空，写入下面的一坨：

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

写入后，sudo apt-get update

成功！

但是报了一坨这个：

这能忍么，对于我这么追求完美的人，不能忍，最后找到永久解决的办法：

首先先把/var/lib/apt/lists 的文件备份一下 (养成备份的好习惯)

mkdir /var/lib/apt/list

cp -r /var/lib/apt/lists/* /var/lib/apt/list

然后删除/var/lib/apt/lists/文件夹下所有的文件

rm -rf /var/lib/apt/lists/*

然后打开/etc/apt/sources.list

vim /etc/apt/sources.list

写入阿里源
