Change of default /usr/local/python3 from python3.8 to python3.12 breaks library imports

[mika-b]

Describe the bug
Python 3.12 installed from a PPA conflicts with libraries from the official repositories. If newer python is required, better solution would be to update the base image to v1.48.0-jammy or v1.48.0-noble.

To Reproduce
Steps to reproduce the behavior:

• Launch container and try to import urllib3 in python

docker run -ti --rm marketsquare/robotframework-browser:18.9.1 bash
Unable to find image 'marketsquare/robotframework-browser:18.9.1' locally
18.9.1: Pulling from marketsquare/robotframework-browser
Digest: sha256:065293e926afa8db99fb4248287ae65a41eeeda163ed2b6e80b338a4818c6f96
Status: Downloaded newer image for marketsquare/robotframework-browser:18.9.1

    from six.moves.http_client import IncompleteRead as httplib_IncompleteRead

>>> 

Expected behavior
import of urllib3 works when you explicitly use the python provided by the official Ubuntu repositories.

docker run -ti --rm marketsquare/robotframework-browser:18.9.1 bash
pwuser@9519c297bcbf:/$ python3.8

>>> import urllib3

Additional context
Was working fine with 18.8.0

I don’t quite follow, what is actually broken? I see that urllib3 import failed, but as far I can see it’s not Browser library dependency. Therefore I don’t see what is actually broken?

[mika-b]

It's not a Browser library dependency but people use robotframework-browser container to run their test suites with their libraries and other tools. So the python version change breaks any user test library that tries to import for example urllib3.
