I'm having a problem with pyenv, I'm carrying out some tests with the Zorin OS operating system to work with software development. I needed to change the Python version, I installed pyenv. I asked to install a different version of Python than my current version of Zorin OS. I had the error below:
Downloading Python-3.9.18.tar.xz...
-> https://www.python.org/ftp/python/3.9.18/Python-3.9.18.tar.xz
Installing Python-3.9.18...
Traceback (most recent call last):

import _ssl # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?
Please consult to the Wiki page to fix the problem.

I searched and found this pyenv link, showing some necessary libraries. I performed the installation, restarted the machine, but ended up having a problem with SSL. I looked for a solution again, installed the openssl libssl-dev libs, restarted the machine again. Keep having the same problem.
List of libs I have installed
sudo apt update && sudo apt install build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev curl \
libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev gcc openssl libssl-dev
Try installing those libs
sudo apt-get update; sudo apt-get install --no-install-recommends make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
Then run pyenv install -l to see available versions, and install wanted version.
Also, if that does not work you can try this command for necessary libs.
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
Good luck, hope this will help. I would really appreciate some feedback about it :)
If nothing works you should try reinstalling everything.
