ERROR! We were unable to read either as JSON nor YAML, these are the errors we got from each:
JSON: Expecting value: line 1 column 1 (char 0)

Syntax Error while loading YAML.
  did not find expected alphabetic or numeric character

The error appears to be in '/home/cjac/ansible/apt-upgrade.yml': line 5, column 14, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  - apt:
      name: *
             ^ here
