Can it be reopened until the issue is fixed on Ansible rpm packaging side? It is there RH Bugzilla or issue already posted anywhere?

@tutunak your workaround works for me thanks! Snippet for anybody else:

sudo yum -y remove ansible
pip3 install ansible --user
pip3 install "molecule[lint]" --user
pip3 install "molecule[docker]" --user

[tutunak]

I’ve removed molecule from pip3 and pip2, remove ansible by dnf and then install ansible and molecule from pip3 and it’s working fine for me now.
