Trouble running docker registry in insecure mode on Ubuntu 16.04

Question

I'm trying to run a docker registry in insecure mode on ubuntu 16.04 (docker v1.12.3). I made the changes specified in the documentation.

/etc/default/docker:

DOCKER_OPTS="--insecure-registry 10.10.10.10:5000"

and then restarted the docker service. However I'm having no luck. When I try to connect I get

Error response from daemon: Get https://10.10.10.10:5000/v1/_ping: 
http: server gave HTTP response to HTTPS client

Check if this docker/distribution issue could help (when used with docker 1.12):

Create or modify /etc/docker/daemon.json

    { "insecure-registries":["myregistry.example.com:5000"] }

Restart docker daemon

    sudo service docker restart

On Unbuntu 16.04, check also if configuring docker through systemd is better.
