...with the following error:

----------
          ID: aptly_user
    Function: user.present
        Name: aptly
      Result: False
     Comment: Failed to create new user aptly
     Started: 13:14:41.167389
    Duration: 24.448 ms
     Changes:

in the logs state is rendered as below:

aptly_user:
  group.present:
    - name: aptly

  user.present:
    - name: aptly
    - shell: /bin/bash
    - home: /var/lib/aptly

    - require:
      - pkg: aptly_packages

command fails with:

to fix it just add else:

    {% if aptly.user.gid %}
    - gid: {{ aptly.user.gid }}
    - gid_from_name: True
    {% else %}
    - gid: {{ aptly.groupname }}
    {% endif %}

let me know if I misunderstood something.
