With the important line being:

WARNING: Discarding git+https://github.com/systemd/python-systemd.git#egg=systemd. Requested systemd-python from git+https://github.com/systemd/python-systemd.git#egg=systemd has inconsistent name: filename has 'systemd', but metadata has

So I changed the command to:

/usr/local/lib/docker/virtualenv/bin/pip3 install -U --force-reinstall -v git+https://github.com/systemd/python-systemd.git#egg=systemd-python

which worked. I'm assuming that it's just a documentation issue?

This is also stemming from the fact that the version in pypi is 0.0.9, which does not have the systemd.daemon.listen_fds() function available.

I have the same issue in ubuntu 20.04 installing in a virtual environment
