一：問題概述
Ubuntu，我們在使用apt新裝軟件的時候，會使用官方的網(wǎng)站去下載軟件，但是會因為國內(nèi)的轉(zhuǎn)接點太多，而導(dǎo)致下載的速度非常慢 ，我們可以通過換成一些中間的節(jié)點來進行下載，比如阿里源，中科大源，清華源等等，這樣的網(wǎng)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件的速度。
二：ubuntu系統(tǒng)更換源
更換源的方法非常簡單:修改/etc/apt/sources.list文件即可
- 1：進入/etc/apt/ ,
cd /etc/apt- 2：修改
sources.list文件,sudo vi sources.list(要有管理員權(quán)限)- 3：可以在修改前先對
sources.list文件進行備份
sudo cp sources.list sources.list.bak- 4:刪除掉
sources.list的其他內(nèi)容，任意選擇一種源的內(nèi)容復(fù)制粘貼進去，保存，例如，選擇阿里源- 5:更新apt
sudo apt-get update
三：ubuntu各個版本的阿里云源內(nèi)容
