Ubuntu18.04更改apt国内源

前言

Ubnutu默认的源在墙外,慢的不行。100多kb,等得我发慌。国内ubnutu的apt源很多,比如:阿里、网易、清华、中科大。感觉都差不多,我下边都会提供的,大家看心情用。以下教程一阿里源为例。

教程

1.先备份默认源文件(/etc/apt/sources.list)以防万一

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

2.编辑默认源文件

sudo gedit /etc/apt/sources.list

执行命令后就打开了/etc/apt/sources.list文件,将文件内的所有文件全部删除。
将下边的源添加到文本中,保存保存保存(重要的事)。之后关闭即可。

3.更新源

sudo apt-get update
sudo apt-get upgrade

至此更新apt源完成。
