Support Debian 13

[matt-hh]

Hi, i found an issue with Debian 13:

fatal: [xxxxx]: FAILED! => {"attempts": 20, "changed": false, "msg": "No package matching 'software-properties-common' is available"}

My workaround is to redefine docker__package_dependencies without "software-properties-common":

- name: Install Docker
  hosts: all
  roles:
    - role: "nickjj.docker"
      tags: docker
  vars:
    docker__package_dependencies:
      - "apt-transport-https"
      - "ca-certificates"
      - "cron"
      - "gnupg2"

Does anyone know how to change defaults/main.yml to use a different docker__package_dependencies variable on Debian 13?

You can define docker__package_dependencies in the group vars or host vars for any hosts that use Debian 13.

You'd configure it the same way, except instead of being in the playbook for all hosts, it would be in group_vars/somehost.yml or host_vars/somehost.yml where somehost.yml is your Debian 13 box. This is general purpose Ansible inventory management.

What you have now also works if you want to use that configuration for all of your hosts that are using Docker.

@matt-hh, you can skip the dependency on Debian 13+ by specifying software-properties-common conditionally:

- "{{ 'software-properties-common' if ansible_distribution != 'Debian' or (ansible_distribution == 'Debian' and ansible_distribution_major_version|int <= 12) else omit }}"

See my pull request #133 for details.
