Unable to install nodejs from nodesource apt repo with apt module

Anyone by chance know why this is no longer working on ansible 2.0.0.2?

The apt repo definition is deb https://deb.nodesource.com/node_4.x trusty main

- name: install packages
  apt:
    name: "{{item}}"
    state: present
    update_cache: true
  with_items: apt_packages
  register: apt

What is “Could not fetch updated apt files”? Seem to be working until we had to install the dependencies here (https://groups.google.com/forum/#!topic/ansible-project/dFRlLiUI4PA)

Seems to not bespecific to node, but when update_cache: true.
