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, 🙂  
Andrew
