当我尝试使用各种命令或未安装的软件包时，会出现此错误消息：
Traceback (most recent call last):
File "/usr/lib/command-not-found", line 28, in <module>
from CommandNotFound import CommandNotFound
File "/usr/lib/python3/dist-packages/CommandNotFound/CommandNotFound.py", line 19, in <module>
from CommandNotFound.db.db import SqliteDatabase
File "/usr/lib/python3/dist-packages/CommandNotFound/db/db.py", line 5, in <module>
import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'
我努力了这个答案但是当我使用sudo apt autoremove,sudo apt autoclean或sudo apt remove python3-apt出现此错误消息时：
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
