Ansible-playbook succeeds with no changes but i686 package not installed

Hi there,

I’m a new user to Ansbile so this might well be user error but I’m seeing ansible-playbook complete with no issues but not update the dnf package. Edit: after a bit of debug as I wrote this issue, it looks like the problem is only with i686 packages.

Ansible version: core 2.17.0

My playbook looks like:

---
- hosts: rhel
  become: yes

  tasks:
    - name: RHEL specific packages
      dnf:
        name:
          - glibc-devel
          - glibc-devel.i686
      when: ansible_facts['os_family'] == 'RedHat'

and my invokation and stdout looks like:

$ ansible-playbook playbooks/test.yaml -K
BECOME password:

Is this a bug or do I need to do something else to allow Ansible to install i686 packages?

Thanks, Shareef.

I’m afraid I’m not a RedHat user these days, but on Debian / Ubuntu one would first need to add the architecture prior to installing a package, the package architecture in this case would be added to the package name separated with a colon, something like this:

- name: Architecture i386 enabled
  ansible.builtin.command: dpkg --add-architecture i386

- name: Linux support headers for userspace development present for i386 and x86_64
  ansbile.builtin.apt:
    pkg:
      - linux-libc-dev
      - linux-libc-dev:i386

Perhaps something like this is also needed for RedHat based distros?

Thanks, I can add it manually without any further dnf magic. It’s just not being installed by Ansible.

Edit: and wouldn’t you expect an error if that were the case rather than failing silently?
