Create Virtual Environment with native Python (w/out Conda

Goal: create Python 3.8.8 venv.

I've Python 3.8.10 installed
Poetry project is Python 3.8.8
don't have conda

I tried installing suggested package for creating a venv but this didn't work.

How can I create a Python 3.8.8 venv without conda?

Terminal:

@PF2DCSXD:/mnt/c/Users/me/Documents/GitHub/foo/bar$ poetry install
The currently activated Python version 3.8.10 is not supported by the project (3.8.8).
Trying to find and use a compatible version. 

  NoCompatiblePythonVersionFound

  Poetry was unable to find a compatible version. If you have one, you can explicitly use it via the "env use" command.

The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt install python3.8-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: ['/mnt/c/Users/me/Documents/GitHub/foo/bar/sdg/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']

See one of the links below:

https://python-guide-cn.readthedocs.io/en/latest/dev/virtualenvs.html or https://virtualenv.pypa.io/en/latest/installation.html

But I strongly recommend to use conda for create and manage venv
