Execute module only, if package is installed

[Denny Fuchs]

hi,

I'm pretty new to Ansible (2.8 on Debian Stretch) and we have very simple playbook for upgrading packages, including run rkhunter / puppet / reboot etc. My problem is, that I do not have puppet an all nodes installed, so I tried:

---

#vim:ts=2:sts=2:sw=2:et

  - hosts: all

    serial: 1

    tasks:

      - name: Gather package facts

        package_facts:

          manager: auto

      - name: Run puppet to apply last changes

        puppet:

      - include_tasks: update_packages.yaml

      - include_tasks: reboot.yaml

      - name: "Puppet test result"

        debug:

          msg: "Puppet found"

        when: "'puppet' in ansible_facts.packages"

      - name: Run puppet to fix possible changes

        puppet:

Problem is: on  nodes where "puppet" is installed, puppet is skipped and on nodes, where puppet is NOT install, the task fails. What I'm doing wrong ?
