记录ubantu 22.0.4 安装 yum提示无法找到包

1、 sudo vim /etc/apt/sources.list

执行命令修改源目标，ubuntu | 镜像站使用帮助 | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror

选择好版本复制然后全部替换

2、可以直接复制使用

3、 更新源文件

apt-get update

apt-get upgrade

4、安装yum

 apt install yum

如果提示错误，有包未安装，如libpython-stdlib，可以直接执行apt install libpython-stdlib，然后重新安装yum

ps:为什么ubantu想装yum,ubantu自带的apt其实就相当于yum
