Patch to fix: "ANXS.apt : APT | Install Packages failed with No package(s) matching '['python3-apt'' available" error

[ianheggie]

I refactored out the combining of the two lists (see patch below) and that fixed the problem for me!

Environment:

• roles/ANXS.apt/version: v2.1.0
• ansible --version: ansible [core 2.14.6]
• ansible_python_interpreter: /usr/bin/python3
• os-release (host and target): VERSION="22.04.2 LTS (Jammy Jellyfish)"
• defaults/main.yml vars not overriden

Log from ansible:

Patch that fixed the problem for me (personally prefer running apt on default separately from version specific list anyway)

@ianheggie actually the issue is related to changed arithmetic and concatenation operations outside of the jinja template.
The solution is to change this {{ apt_default_packages }} + {{ apt_default_packages_pre20 }} to this {{ apt_default_packages + apt_default_packages_pre20 }}

edit: I've just realized that the fix is already merged ;)

Thanks for your feedback - I didn't twig to that being the issue. I was just reading about "egg of Columbus" and your solution fits!
