Hi Loïc, I also realized that might be a problem in an old version. So I upgraded the snapd to the latest version.
$ snap --version snap 2.16ubuntu3 snapd 2.16ubuntu3 series 16 ubuntu 16.04 And I tried to install the docker from both stable and edge channel. In both cases, the plug and slot can not connect problems have gone. But I am still not able to figure out how to run a simple hello world docker. $ docker run ubuntu /bin/echo 'Hello world' docker: Cannot connect to the Docker daemon. Is the docker daemon running on this host?. See 'docker run --help'. Thanks.
