Python Updater for Ubuntu

This script updates all active releases of Python, even the pre-release ones. This is for people who likes building things from source because mental health is not a thing for you.

If you have a script that runs on an end of life Python version, it's best to find another repository that hasn't been abandoned for over 5 years.

For the change log please check CHANGELOG.md

Future Plan

Feel free to contribute your code, if anyone sees this at all.

• Passing arguments such as ./main.sh 3.12 will check the specific version only

How does this work?

1. Dependencies are either updated or installed. The list comes from the developer's guide of Python.
2. Using wget, release information is extracted from the Python download and pre-release pages.
3. Using a bunch of greps, a list of all releases is generated. The list is sorted with sort -Vr, so the newest version is head -n 1.
4. Your python version is checked, if it does not exist, the version will be None.
5. All active Python versions will be updated/installed based on that information.

Note: All python will be installed in /usr/local/bin so it doesn't interfere with the system's python3 (For noobs: Don't change the system python version, it breaks things).
