一、前言
系统还换源，为了联网更新包时更快，不同系统对应的源也不同，这里其实与硬件就没有关系了，主要是看文件系统是什么版本，目前主流的系统ubuntu18.04 ubuntu20.04 ubuntu22.04 银河麒麟V10 SPI等等，这几个也是我常用的，后续有其他在持续更新
目录
ubuntu源
银河麒麟源
二、环境
RK3588（linux5.10.66+debian/ubuntu/麒麟是桌面文件系统）
调试笔记本window10，安装常用工具winscp，xshell，finalshell，secureRTP等等
VMware17+Ubuntu20.04源码开发环境（这里就依赖于各个硬件平台的厂家提供资料了）
三、正文
1.执行命令，进入vim编辑，没有vim安装sudo apt-get install vim（在更改之前最好备份一下，但是方法对了，备份也没啥用，就算上个保险吧）
sudo vim /etc/apt/sources.list
或者
sudo gedit /etc/apt/sources.list
2.
输入:%d来删除文件中的所有内容。
按下Enter键执行删除命令
按i进入编辑模式，右键复制源
之后esc，在：wq保存
3.执行更新软件列表sudo apt-get update
4.执行更新软件sudo apt-get upgrade
我这有几个，大家也可以随便百度和AI查询，太多了，我列不全
