my jenkins config is now:

# https://github.com/WDscholia/scholia/issues/2183#issuecomment-1356768054
python3.12 -m venv .venv
source .venv/bin/activate
python --version
# make sure we use the proper tox .ini
cp -f /home/wf/.scholia/tox.ini ./tox.ini
# 2. Verify the copy happened (prints the first few lines to log)
head -n 5 tox.ini

# Run tests (py312) and linting (flake8)
/home/wf/.local/bin/tox -e py312,flake8

tests run flake8 does not work yet
