doc8: install_deps> python -I -m pip install -r /w/workspace/oom-master-doc8-lint/requirements.txt -c https://git.onap.org/doc/plain/etc/upper-constraints.onap.txt

The conflict is caused by:
    The user requested sphinx>=7.2.0
    The user requested (constraint) sphinx===7.1.2

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict
