ubuntu换国内源

为什么需要换源

      ubuntu默认的软件源服务器是在国外的，下载速度堪称龟速，更恶心的是，可能在你等了几个小时之后，给你一个failed,所以，为了防止抑郁，在愉快享用ubuntu之前，一定先换源

      具体理解什么是源，为什么需要换源，请参考：https://www.zhihu.com/question/413453462

换源的具体步骤（以阿里源为例）

 备份原来的源      sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

 

打开sources.list文件

sudo gedit /etc/apt/sources.list

 

删除sources.list文件在原有的内容，把阿里源的内容粘贴进去，保存，退出
