最近在安装环境时执行apt-get update或者upgrade时，总是报错:

安装进行不下去，之前好好的，怎么会出现这种奇怪的事呢，按理说apt-get update是Ubuntu最核心和常用的工具了，不大可能会没有正确安装的，仔细想想安装环境过程中都做了些什么，这个 import debian.deb822报错应该是python相关的东西，那最有可能是python安装不对或者版本不对了，于是突然想起为了满足实验某模型的要求安装了个很新的python3.9.6，并且把/usr/bin/python3指向了python3.9.6，可能就是这个python版本太高了的原因引起的，于是删掉/usr/bin/python3，重新创建链接指向python3.6.8，再执行apt-get update就正常了！

没有reinstall,sudo apt remove python3-debian && sudo apt install python3-debian

亲测: 其实可以执行`sudo apt reinstall python3-debian` 以修复.
