NOTE: Internet is enabled, please use the provided qemu image, and note that this has been tested to work in a Debian environment for the Docker host. An Ubuntu host is known to have issues with the official solution for the challenge. If you are on Debian, the docker deployment should work for you if you don't want to use the qemu image (but not guaranteed).
