我们需要根据我们自己Ubuntu系统版本来配置对应的apt源
一、常见LTS版本代号
- Ubuntu 20.04代号为：focal
- Ubuntu 19.04代号为：disco
- Ubuntu 18.04代号为：bionic
- Ubuntu 17.04代号为：zesty
- Ubuntu 16.04代号为：xenial
二、查看linuxOS发行版本信息
查看命令：
lsb_release -a
ubuntu 20.04 ==> 发行版本代号为 focal
$ lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 20.04.1 LTS
Release: 20.04
Codename: focal
ubuntu 18.04 ==> 发行版本代号为 bionic
$ lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 18.04.6 LTS
Release: 18.04
Codename: bionic
三、修改apt源
1. 修改sources.list文件
sudo gedit /etc/apt/sources.list
ubuntu 20.04
