我是靠谱客的博主清爽夕阳，最近开发中收集的这篇文章主要介绍sudo apt-get update 各种问题！（ubuntu 16.04），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

不知道大家最害怕什么linux命令，我最最最最害怕的就是 sudo apt-get update命令。我简直遇到了各种各样形形色色的问题，甚至有一些是网上找不到原因，最后不知道改了什么，莫名其妙又好了的问题。气到肝疼！

今后遇到的apt-get update 问题全都归纳总结到这里，做个记录，看能遇到多少！

会持续更新，一有问题就更新！

E: Some index files failed to download. They have been ignored, or old ones used instead.

解决方法：

换成阿里源（额。。。其实我之前用的就是阿里源，相当于重新粘了一遍，私以为这步没用）

sudo apt-get clean(好像没有成功，不过懒得管了)

sudo rm /var/lib/apt/lists/* -vf

错误瞬间变成了如下：

换了个我也不知道是哪里的源(原谅我的孤陋寡闻)，竟然可以了！果然是源的问题吗？

sudo gedit /etc/apt/sources.list

将/etc/apt/sources.list文件替换为下面文件

deb http://cn.archive.ubuntu.com/ubuntu/ xenial-updates main restricted universe multiverse
