The collection bindep is hardcoding python version

[lucas-benedito]

SUMMARY

While installing the collection and using the bindep offered by the same, my build ended up installing python38 due to the hardcoded bindep with python38-lxml

ansible_config: 'ansible.cfg' 

dependencies:
  galaxy: requirements.yml

requirements.yml
---
collections:
  - name: cisco.iosxr
    version: "5.0.1"

EXPECTED RESULTS

Dependencies installed from Python 3.9

ACTUAL RESULTS

- 'python38-lxml [platform:centos-8 platform:rhel-8]  # from collection cisco.iosxr'

[NilashishC]

@lucas-benedito Do you mean that installing python38-lxml downgrades the Python version in ee-minimal-rhel8 to Python 3.8?

[lucas-benedito]

@NilashishC it forces the installation of both versions as the package name enforces python 3.8. This causes a mismatch where the execution environment discovered python is 3.9 but the libraries are installed in 3.8

[NilashishC]

@lucas-benedito Ah, I see. I get it now. Thanks for the info.

[NilashishC]

This should be resolved if we use python3-lxml instead.

(nchakrab) $ podman run -it registry-proxy.engineering.redhat.com/rh-osbs/ansible-automation-platform-23-ee-minimal-rhel8 /bin/bash

Yes, the problem is that we use a discovery from the collection and if the bindep that comes with it shows a mixed of python 39 and 38 then it leads to the issue informed.
