一：問題概述

  ubuntu，我們在使用apt新裝軟體的時候，會使用官方的網站去下載軟體，但是會因為國內的轉接點太多，而導致下載的速度非常慢 ，我們可以通過換成一些中間的節點來進行下載，比如阿里源，中科大源，清華源等等，這樣的網站，他們會定時和官方的源進行同步和更新，而我們直接同步他們，速度就會比直接同步官方的源快很多，這樣能夠大大增加我們的下載軟體的速度。

二：ubuntu系統更換源

 更換源的方法非常簡單:修改/etc/apt/sources.list檔案即可

###2.1：進入/etc/apt/

cd /etc/apt

2.2：修改sources.list檔案

sudo vi sources.list 
 

2.3：可以在修改前先對 sources.list檔案進行備份

sudo cp sources.list sources.list.bak

2.4:刪除掉sources.list的其他內容，任意選擇一種源的內容複製貼上進去，儲存，例如，選擇阿里源

2.5:更新apt

sudo apt-get update

三：ubuntu各個版本的阿里雲源內容
