问题
我正在运行 Ubuntu 20.04 LTS。我安装了 Python 3.8 和 Python 3.9，但 Python 3.8 有问题。当我在终端中
输入命令时，我得到以下内容：python3.8
root@ubuntu-3pl:~# python3.8
Fatal Python error: init_import_size: Failed to import the site module
Python runtime state: initialized
Traceback (most recent call last):
File "/usr/lib/python3.9/site.py", line 79, in <module>
import os
File "/usr/lib/python3.9/os.py", line 29, in <module>
from _collections_abc import _check_methods
File "/usr/lib/python3.9/_collections_abc.py", line 12, in <module>
GenericAlias = type(list[int])
TypeError: 'type' object is not subscriptable
在我看来，这就像是python3.8在挖掘/usr/lib/python3.9，也就是python3.9的库。
以下是一些命令的输出：
root@ubuntu-3pl:~# which python3.8
/usr/local/bin/python3.8
root@ubuntu-3pl:~# which python3
/usr/bin/python3
root@ubuntu-3pl:~# /usr/bin/python3 --version
Python 3.9.5
root@ubuntu-3pl:~# python3
Python 3.9.5 (default, Nov 23 2021, 15:27:38)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

Python 3.9 运行良好，但 Python 3.8 显然不行。我希望 Python 3.8 能够正常工作，因为我想安装landscape-common依赖它的各种其他软件包。当我尝试安装时，会发生以下情况landscape-common：
root@ubuntu-3pl:~# apt install landscape-common

问题
我怎样才能：
- 卸载 Python 3.8 的所有痕迹并重新安装成功？
- 修复它以便可以运行吗？
landscape-common使用 Python 3.9安装？
欢迎任何帮助/建议！除了重新安装操作系统之外，我很乐意尝试任何方法。
