Hello Discourse team,
I’m considering using Discourse with a Trisquel 8 Docker image, which should work because Trisquel 8 is based on Ubuntu Xenial. The reason I want to do this is so I can use a fully-free distribution instead of one that includes non-free bits here and there. There is no Trisquel 9 release based on Ubuntu Artful yet, so I was wondering how long you plan on sticking with Ubuntu Xenial? If you continue to use it for a year or two, I might be able to use Trisquel as a base image.
Thanks, : )
Andrew

We have no specific plans to move off Xenial at the current time, but we consider the choice of distro inside the container to be an internal implementation detail, not a public interface, so we may well change the container distro at any time.
Incidentally, I think the inclusion of the `restricted` repo in our container image’s `sources.list` is unnecessary, and can probably be dropped. If we only use the DFSG-free `main` and `universe` repos, doesn’t that produce the same end result as using a different underlying distro?

Hello Matt,
Thanks for your reply. I started a conversation about the repo types here a while back:
> [@Docker image includes unneeded Ubuntu "restricted" (non-free) repo](https://meta.discourse.org/t/docker-image-includes-unneeded-ubuntu-restricted-non-free-repo/88931/2):

> I believe this come from our upstream docker image, at this line That line points to the official Ubuntu image from the Docker library which has this line: where it adds [this archive](https://github.com/tianon/docker-brew-ubuntu-core/blob/dist-amd64/xenial/ubuntu-xenial-core-cloudimg-amd64-root.tar.gz) that contains the restricted lines you found. I don’t know if there is an official Ubuntu docker image with those disabled.
Using `main` and `universe` alone would be a great improvement. Chances are that you won’t need anything outside of `main`.
The place I work at cares very much about using fully free distributions, so Ubuntu “man” alone might not be sufficient for our purposes, but I’ll talk to my team about it.
Thanks, 🙂

我们已迁移至 Debian，且据我们所知未启用额外的软件源，因此这应能改善您的使用场景。

确实如此！非常感谢您切换到 Debian main！: )
