Azure VM 上的 Ubuntu 18.04.6 LTS 无法运行 apt 升级：ModuleNotFoundError：没有名为“apt_pkg”的模块

当我尝试更新使用 APT 安装的软件时收到此错误消息：

当我运行时也会发生类似的事情neofetch：

$ neofetch
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/db/db.py", line 5, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

我做的最后一件重要的事情是安装 Python 3.10，一切应该顺利。我不知道我做错了什么。

编辑：正如有人建议的那样，我已经尝试运行该命令apt-get install --reinstall python3-apt，但它并没有解决问题：

$ sudo apt-get install --reinstall python3-apt

尝试给出的答案更新管理器出现问题：Ubuntu 13.10 中没有名为“apt_pkg”的模块，在 /usr/local/lib 上安装了 Python 3.4

sudo apt-get install --reinstall python3-apt
