It would be great if the changes could also be upstreamed to:

https://github.com/docker/docker-ce

So that the people using the Docker website instructions and repository also don't need to pull down python2 as a dependency.

The no python2 by default effort for 16.04 seems to have lost most of its momentum. Is this no longer a priority for Canonical for Ubuntu? While the 16.04 goal has long since passed, there is another opportunity to clean up the repos for 18.04.

Status changed to 'Confirmed' because the bug affects multiple users.

seems crazy to install the full python2 stack to just get docker-compose. As a workaround I installed python3-pip and installed docker-compose through pip.
