Check if security updates needed on Ubuntu servers

Here's an Ansible playbook that will output a message for each server that requires a security update.

- name: check if security updates are needed
  hosts: myhosts
    - name: apt-check
      shell: "/usr/lib/update-notifier/apt-check 2>&1 | cut -d ';' -f 2"
      changed_when: false
      register: security_update

    - debug: msg="Security update required"
      when: security_update.stdout != "0"
