Port from Python 2.7 to Python 3

This code base is in need of modernization. An updated version of Raspbian in the container would also be helpful.

Hello!

I am getting familiar with this application. I have successfully launched it locally with Docker using the following Dockerfile and entrypoint.sh.

FROM --platform=linux/arm raspbian/systemd:latest
workdir /home/chronos

RUN echo "deb http://legacy.raspbian.org/raspbian stretch main contrib non-free rpi" > /etc/apt/sources.list

To approve a PR, the application would need to work without this installation in the Dockerfile, right?

apt-get install python2.7

Apart from updating Raspbian to the newest version known as Raspberry Pi OS.

Hi thanks for looking at this.

Glad the docker build worked for you.

Yes, that's correct.

Would you assign the issue to me? I'm focused on resolving it. @agtic

thank you!

[agtic]

Assigned as requested @Car85. Keep me posted on your progress. Also please monitor the progress on the other open issue on this repo to split the front and backend into separate repos: https://github.com/agtic/chronos/issues/1 @fardin-developer is working on it.

If you get stuck, it might make sense to wait until the other issue is completed.
