    Currently if ensurepip fails for a reason or another, for example if a wrong module gets imported:

    $ touch http.py
$ python3.10 -m venv .venv
Error: Command '['/tmp/.venv/bin/python3.10', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

    the error is not helpfull. Maybe venv should just dump the stderr from ensurepip so we can learn a bit more about it (it's « understandable » in ensurepip traceback that it's in relation with http.py, in the given example.)
