我們需要根據(jù)我們自己Ubuntu系統(tǒng)版本來配置對應(yīng)的apt源

一、常見LTS版本代號

• Ubuntu 20.04代號為：focal
• Ubuntu 19.04代號為：disco
• Ubuntu 18.04代號為：bionic
• Ubuntu 17.04代號為：zesty
• Ubuntu 16.04代號為：xenial

二、查看linuxOS發(fā)行版本信息

查看命令：

lsb_release -a

ubuntu 20.04 ==> 發(fā)行版本代號為 focal

$ lsb_release -a
Distributor ID:	Ubuntu
Description:	Ubuntu 20.04.1 LTS
Release:	    20.04
Codename:	    focal

ubuntu 18.04 ==> 發(fā)行版本代號為 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

2.更新

$ sudo apt-get update
$ sudo apt-get upgrade
