I'm using the docker-ce package from Docker Inc. There is no docker-ce
package in Debian. There was a docker.io in Debian jessie and I just
saw that it is available for buster and sid but that is not what I am
using. Hence, I filed a bug at what I think is the most correct place.

I might give docker.io a try again someday but right now I don't have
the time.

Hope this helps,
