So I decided to install a Linux-based operating system, Docker and all services as Docker containers. But many times, they fall short in functionality and not all services are available as Add-on.

Home Assistant Add-ons are quite useful, they allow you to configure new services in a simple way.

It looks like Debian provides a way to update the system Python version: but using an official package is another thing, as it will also update all other packages depending on Python, critical or not, in an atomic transaction.After trying Home Assistant on a Raspberry Pi 2 for several months, it became necessary to buy a Mini-PC in order to expand the services and devices in my home, that is why I have encouraged myself to buy a Medion S22003 MD34639. That said, I reiterate, if you try to build your own Python and install it over the system's one, you will break your system to re-install needed point. Pyenv - is the the 'de facto' framework to have multiple Python versions in the same system. The correct way to have various, and newer, Python versions in a Linux is to build them to other prefixes (even in the user home, no need for a global Python with other versions), and them leverage on virtaulenvs so that each project, or scratch directory for scripts one have, use the exact desired interpreter. For more than 10 years now, most Linux distributions rely on Python for critical system tasks, including package managing - and replacing the very files of the system Python packages will make all Python extensions in the system utilities to break at once. One should not try to replace the system Python install in any Linux distribution: it will just take your system into an unusable state.
