Hii
"splitpath.py" isn't a valid key for the config file. The correct one
is "filter_plugins", see:
https://docs.ansible.com/ansible/latest/reference_appendices/config.html#default-filter-plugin-path
But I don't see why you would need such heavy weapons if all you want
is a list of package names that have pending updates.
This should roughly do the same, without the complexity of custom filters:
- 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 }}"
- debug: var=updates
