Problem:

Hi @shubham

I had a look at oss.atix.de but did not find any Debian/Ubuntu major version that still uses Python2. I doubt that you can install and use Python 3.8 on Ubuntu 16.04 which is required by python3-subscription-manager for Ubuntu 20.04. So this hack is probably not gonna work. Therefore, I assume that you’ll have to either package subscription-manager yourself or install by hand using Python tooling.

Thanks @maximilian for your prompt reply,
Is there any easy way to register this host instead of using subscription manager?
I am trying to do this using puppet and ansible playbook both, but i am unable to achieve what i want. Please suggest, if you have any simpler way

Ansible playbook-

ansible version- ansible [core 2.16.3]

inventory yml:-

all:
hosts:
target1:
ansible_host:
ansible_ssh_private_key_file:
ansible_user: ubuntu

register_hosts.yml:-

  • name: Register hosts in Foreman
    hosts: all
    become: yes

    tasks:

    • name: Ensure the SSH directory exists
      file:
      path: /root/.ssh
      state: directory
      mode: 0700

    • name: Copy Foreman SSH key to target machines
      copy:
      src: /usr/share/foreman-proxy/.ssh/id_rsa.pub
      dest: /root/.ssh/authorized_keys
      owner: root
      group: root
      mode: 0600

    • name: Install required packages
      package:
      name:
      - facter
      - python3
      state: present

    • name: Report to Foreman (using callback plugin)
      debug:
      msg: “Host reported to Foreman via callback plugin.”

Output:-

ansible-playbook -i inventory.yml register_hosts.yml

Without subscription-manager you won’t be able to register a host.
