Comment 5 for bug 1995249

Ansible provides very clear requirements on its github where it say Ansible 2.12.X needs resolvelib >= 0.5.3, < 0.6.0 but you are forcing resolvelib to be 0.8.1 when installing ansible with apt.

https://github.com/ansible/ansible/blob/stable-2.12/requirements.txt

So either fix the resolvelib version and publish the old resolvelib or update to Ansible 2.13 where resolvelib can be resolvelib >= 0.5.3, < 0.9.0

I managed to fix this by installing first ansible-core with apt and afterwards, installing with pip the resolvelib 0.5.4
