sudo vi /etc/apt/sources.list

    请选择和系统对应的版本，查看系统版本命令：

    lsb_release -a

     Distributor ID: Ubuntu

     Description:    Ubuntu 22.04 LTS

     Release:        22.04

     Codename:       jammy

Ubuntu不同的版本配置的有区别

每个版本的代号是不一样的，比如：

Ubuntu 15.04 代号为：vivid

Ubuntu 16.04代号为：xenial

Ubuntu 17.04代号为：zesty

Ubuntu 18.04代号为：bionic

Ubuntu 19.04代号为：disco

Ubuntu 20.04 代号为：focal 

Ubuntu 22.04 代号为：jammy （果酱的）

    国内的更新源有多个，几个大互联网公司的源都比较稳定，没什么差别。

    这里整理的比较主流的、常用的几个LTS版本的更新源。
