rhel-system-roles.selinux Fatal error

[Kannan]

Dear Team,

I am new to Ansible and i am getting the following erro while running " rhel-system-roles.selinux". Could you please help to resolve this error.

Environment:

RHEL-  9

Ansible core - 2.12.2

 python version = 3.9.10

TASK [rhel-system-roles.selinux : Install SELinux python2 tools] *********************************************************

fatal: [ss1]: FAILED! => {"msg": "The conditional check 'ansible_python_version is version('3', '<')' failed. The error was: error while evaluating conditional (ansible_python_version is version('3', '<')): 'ansible_python_version' is undefined\n\nThe error appears to be in '/usr/share/ansible/roles/rhel-system-roles.selinux/tasks/main.yml': line 2, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n---\n- name: Install SELinux python2 tools\n  ^ here\n"}

Thanks & Regards,

Kannan Ravi

The error was: error while evaluating conditional (ansible_python_version is version('3', '<')): 'ansible_python_version' is undefined

I don't know why that would not be defined, but that is causing your error.

Hi,

this var needs gather_facts to be true or setup to be called with at least ‘min’ level of facts.

[Richard Megginson]

What version of rhel-system-roles are you using?  Current versions of the role have logic to explicitly call `setup` to get the facts required by the role:

https://github.com/linux-system-roles/selinux/blob/master/tasks/set_facts_packages.yml#L2

and python_version is among the facts:

# ansible_facts required by the role
__selinux_required_facts:
  - distribution
  - distribution_major_version
  - python_version

Since you are using rhel-system-roles, this means you are a RHEL and/or an Ansible customer.

If you installed the rpm, use rpm -q rhel-system-roles

If you installed from AutomatIon Hub, use ansible-galaxy collection list or something like that.
