No module named 'distutils.util' ...but distutils is installed?

I was wanting to upgrade my Python version (to 3.10 in this case), so after installing Python 3.10, I proceeded to try adding some modules I use, e.g., opencv, which ran into: ```lang-none python3.10 -m pip install opencv-python ``` Output: ```lang-none Traceback (most recent call last): File "/usr/lib/python3.10/runpy.py", line 196, in _run_module_as_main return _run_code(code, main_globals, None, File "/usr/lib/python3.10/runpy.py", line 86, in _run_code exec(code, run_globals) File "/usr/lib/python3/dist-packages/pip/__main__.py", line 16, in <module> from pip._internal.cli.main import main as _main # isort:skip # noqa File "/usr/lib/python3/dist-packages/pip/_internal/cli/main.py", line 10, in <module> from pip._internal.cli.autocompletion import autocomplete File "/usr/lib/python3/dist-packages/pip/_internal/cli/autocompletion.py", line 9, in <module> from pip._internal.cli.main_parser import create_main_parser File "/usr/lib/python3/dist-packages/pip/_internal/cli/main_parser.py", line 7, in <module> from pip._internal.cli import cmdoptions File "/usr/lib/python3/dist-packages/pip/_internal/cli/cmdoptions.py", line 19, in <module> from distutils.util import strtobool ModuleNotFoundError: No module named 'distutils.util' ``` And ```lang-none sudo apt-get install python3-distutils ``` Output: ```lang-none [sudo] password for jeremy: Reading package lists... Done Building dependency tree Reading state information... Done python3-distutils is already the newest version (3.8.10-0ubuntu1~20.04). ... 0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded. ``` Since distutils already seems to be installed, I can't grok how to proceed.
