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

Status: Downloaded newer image for marketsquare/robotframework-browser:18.9.1

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.

@mika-b Sorry to play "bad cop" here.

But even if Python 3.12 would break urllib3, which it doesn't, Python 3.12 is an official release for over a year now. 3.13 is pretty new, but every maintained library should be compatible to 3.12 by now.

By the way urllib3 and six are compatible and i am convinced that this happens because there are old versions of libraries on the system.

We have to test, if this is something that we can control, or if this is in your projects dependencies. Something is not up to date.

Please verify if you are using maintained versions of your libraries. All hints in the search i did, do confirm that older versions were incompatible, but that this has been fixed.

Decided to fix it be removing the urllib3 and six from docker package.
