How you can implement this depends on the feature you need
1. one server having a several repo stable, testing and unstable
2. one server only having stable, testing or unstable.
My first approach was to concentrate all the ansible-managed *.list
files under a common prefix, zda, giving, for example,
zda-unstable.list.
I then wrote code to first remove all zda*.list files (and their
laegacy-named
instances), and code to deploy the correct zda-foo.list file:
- name: search for sources.list files
find:
paths: "/etc/apt/sources.list.d"
patterns:
"zda-*.list,exp-mc.list,sid-mc.list,sid-zg-stable-mc.list,sid-zg-unstable-mc.list,stretch-mc.list,stretch-security.list,stretch-zg-stable-mc.list,stretch-zg-unstable-mc.list,buster-mc.list,stretch-zg-stable-mc.list,stretch-security.list"
register: sourceslistfiles
- name: delete sources.list files
file:
path: "{{ item.path }}"
state: absent
with_items: "{{ sourceslistfiles.files }}"
To clean up legacy I would only run this once and after that make
Ansible do the work.
and finally code to roll out new list files:
- name: include repositories
tags:
repos
include_tasks:
"{{distribution}}/{{distribution_version}}/repos.yml"
$ cat roles/common/tasks/debian/stretch/repos.yml
---
- name: zda-stretch-mc.list
tags:
- repos
- stretch
copy:
dest: /etc/apt/sources.list.d/zda-stretch-mc.list
owner: root
group: root
mode: 0644
content: |
deb http://debian.debian.zugschlus.de/debian/ stretch main
contrib
notify: apt update
- name: zda-stretch-security.list
tags:
- repos
- stretch
copy:
dest: /etc/apt/sources.list.d/zda-stretch-security.list

stretch/updates main contrib
deb http://security.debian.org/ stretch/updates main
contrib
notify: apt update
Feature 1 only need one variable, call it "repo_type", this could
contain stable, testing or unstable.
Then your tasks would look something like this
- apt_repository:
repo: deb http://debian.debian.zugschlus.de/debian/ stretch main
contrib
filename: zda-stretch-mc
state: "{{ (repo_type == 'stable') | ternary('present', 'absent')
}}"
State present creates the file, and absent remove the file so Ansible
will clean up the files so nothing is left behind when you change
repo_type.
You would need one for each repo and repo_type.
But with with_items and facts you could probably make a loop to deal
with most of them.
With feature 2 you could have something like stable_state, testing_state
and unstable_state and set them to absent or present, and then just use
that variable in state.
Hopefully this make some sense.
