Docker dependency errors when using docker_image on Ubuntu 14.04

Unable to use the docker_image Ansible module:

Previously when this issue had occurred #135, I was able to workaround by purposefully pinning docker-compose and docker-py to older versions. I know that prior to Ansible 2.3 this was a
known issue as well ansible/ansible/issues/20492, and that docker-py is now docker and that ansible 2.3 should now work correctly with docker-py 2.0+ per ansible/ansible/pull/19633. I have tried pinning versions again as suggested elsewhere for angstwad.docker_ubuntu users but to no avail. I have removed all pip packages, built fresh instances to test different lower pinned versions etc. I have been going mad over this especially since I have been able to use the docker_image and docker_container Ansible modules in other playbooks as well, hoping someone else has also seen this or I am missing something very obvious.

for now I am just ensuring that I use v2.2.3 of angstwad.docker_ubuntu and make sure to pin

pip_version_docker_py: '1.10.6'
pip_version_docker_compose: '1.9.0'

I want to spend more time understanding exactly why I was having issues on v2.4.2 but was rather blocked by this so will need to circle back at a later point.

FYI, this also happens for me on Ansible 2.2.x. @shanedroid 's solution did the trick. Thanks!

this issue appears to be resolved from https://github.com/angstwad/docker.ubuntu/tree/v2.3.0 onward, I was able to update to latest release of the role with ansible 2.4.3.0 with no issues. 😀
