Again, thanks for this MR, that could be useful to many users.

Would you mind extending this idea a little, please ?

• If we want to let the user replace deb.debian.org by another mirror, then we need to organise this differently, IMHO. For instance, by creating a mirror variable, with the default being deb.debian.org, and then, allow the users to override them.
• Second, as this is a very sensitive value, then I would like to check that the value is valid before deploying the sources.list file, for instance by downloading first the release file (e.g. https://debian.mirror.serversaustralia.com.au/debian/dists/bookworm/Release)
• Last but not least, documentation will need to mention this at least.

Again, thanks for your idea, I never thought about this.

1. Added mirror variable to 'system settings' of each config/defaults/version-*.yml file, added discriptive comment.

2. My skills at ansible are not very strong, so maybe checking code could be done more efficiently, but it passes:

ROLE=bootstrap ansible-playbook -e version=small check.yml

...
TASK [bootstrap : Initialise and update the packages repository] ***********************************
included: ~/Projects/homebox-all/homebox/roles/bootstrap/tasks/check/apt.yml for homebox
TASK [bootstrap : Check apt mirror is valid for us] ************************************************
ok: [homebox] => (item=bookworm)
ok: [homebox] => (item=bookworm-updates)
ok: [homebox] => (item=bookworm-backports)
TASK [bootstrap : Check if we can run apt update without error] ************************************
...

3. Added to section System settings which is IMO self descriptive. Also I'am not sure how to rebuild readthedocs.

Thank you!
Sorry for the late answer, I will check this asap.

@progmaticltd, I've implemented everything as discussed.

Hello, diffway, sorry for the late answer.
Thank you very much, I am testing it right now, and I will come back to you.
The only issue I found so far, is the fact that https does not work with all the mirrors.

Actually, don't do anything, I can automatically detect if the mirror is only compatible with http and write the template accordingly.

@arodier could you kindly make a decision about those conflicts?
I honestly doesn't understand what I'm supposed to do:

the file docs/30-define-your-config.md is gone in progmaticltd:dev
the file roles/bootstrap/vars/main.yml looks fine to me.

Sorry, I neglected this issue, I will come back to it in a few days, during holidays.
