[SOLVED] Delete older kernels in `fedora` after updating OS

Issue

Updating Fedora is strange. Even after several updates, the old versions stick around and use up space on my computer. I'm on Fedora x39 now but want to get rid of the old ones. Any ideas on how to do that?"

I need a way to delete the older kernel in my OS.

Solution

What is the proper method to remove old kernels from a RHEL based system?

To answer in short

dnf remove --assumeyes --oldinstallonly --setopt installonly_limit=2 kernel

In example as an Ansible task

- name: Remove old kernel images
  shell:
    cmd: dnf remove --assumeyes --oldinstallonly --setopt installonly_limit=2 kernel
    warn: false
  register: kernel_removal
  when: ansible_distribution == 'RedHat' and ansible_distribution_major_version | int > 7
  failed_when: kernel_removal.rc != 0 and (kernel_removal.rc != 1 and "No old installonly packages found for removal" not in kernel_removal.stderr_lines)

as the respective Ansible Modules don't handle all of the options.
