Can't install from github?

[davidedelvento]

I'm trying to install stuff from github following the suggestions in issue #21 and the README, but it fails as follows.

My playbook (basically cut-and-paste of the the README):

---
- hosts: all
  roles:
    - tersmitten.r
  vars:
    r_packages:
      - name: mangothecat/franc
        type: github

The error:

< TASK [tersmitten.r : packages | install] >

                ||----w |
                ||     ||

task path: /etc/ansible/roles/tersmitten.r/tasks/packages.yml:24
