一：问题概述

Ubuntu，我们在使用apt新装软件的时候，会使用官方的网站去下载软件，但是会因为国内的转接点太多，而导致下载的速度非常慢 ，我们可以通过换成一些中间的节点来进行下载，比如阿里源，中科大源，清华源等等，这样的网站，他们会定时和官方的源进行同步和更新，而我们直接同步他们，速度就会比直接同步官方的源快很多，这样能够大大增加我们的下载软件的速度。

二：ubuntu系统更换源

更换源的方法非常简单:修改/etc/apt/sources.list文件即可

• 1：进入/etc/apt/ , cd /etc/apt
• 2：修改sources.list文件,sudo vi sources.list(要有管理员权限)
• 3：可以在修改前先对sources.list文件进行备份
  sudo cp sources.list sources.list.bak
• 4:删除掉sources.list的其他内容，任意选择一种源的内容复制粘贴进去，保存，例如，选择阿里源
• 5:更新aptsudo apt-get update
