Unable to install nodejs from nodesource apt repo with apt module

[ja...@blendlabs.com]

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.
