我曾经毫无问题地更新过我的 Python 版本，但我确实注意到，由于未知原因，当我使用“sudo update-alternatives --config python3”更改我的 Python 版本时，我的操作系统无法正常工作
我确实有其他选择：
$ sudo update-alternatives --config python3
There are 3 choices for the alternative python3 (providing /usr/bin/python3).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/bin/python3.8 2 auto mode
1 /usr/bin/python3.10 1 manual mode
* 2 /usr/bin/python3.8 2 manual mode
3 /usr/bin/python3.9 2 manual mode
Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/python3.10 to provide /usr/bin/python3 (python3) in manual mode
如果我不选择python3.8版本，一些系统命令和应用程序将无法运行；
例如，当我将 py 3.9 设置为默认值并尝试运行系统 cmd 时：
$ sudo add-apt-repository ppa:deadsnakes/ppa
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 12, in <module>
from softwareproperties.SoftwareProperties import SoftwareProperties, shortcut_handler
File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 68, in <module>

File "/usr/lib/python3/dist-packages/gi/__init__.py", line 42, in <module>
from . import _gi
ImportError: cannot import name '_gi' from partially initialized module 'gi' (most likely due to a circular import) (/usr/lib/python3/dist-packages/gi/__init__.py)
