Great! Thanks that worked but I had to modify the syntax in the set fact to
make it work.
- name: Check for pending updates
become: true
hosts: all
tasks:
- name: Update cache
apt:
update-cache: yes
changed_when: false
- name: Fetch package list of updates
command: apt list --upgradable
register: aptlist
- set_fact:
updates: "{{ aptlist.stdout_lines | difference(['Listing...'])
| map('regex_replace', '^(.*?)/(.*)', '\\1') | list }}"
