ubuntu_docker_smoke_test / ubuntu_fan_smoke_test failed with "Cannot connect to the Docker daemon" on G-oracle

[Po-Hsu Lin]

Issue found on Groovy oracle 5.8.0-1014.14

Test failed with:
    ++ sudo docker run ubuntu:bionic /bin/sh -c 'cat /etc/lsb-release | grep CODENAME | cut -d '\''='\'' -f 2'
    docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
    See 'docker run --help'.
    + RESULT=
    + '[' '' '!=' bionic ']'
    + echo '** ERROR: The codename returned from lsb_release -c was (' ') and we were expecting bionic'
    + exit 1

As I can see this failure back in history, I won't call this a regression.

This issue does not exist in Groovy generic kernel and other Groovy cloud variants (google / azure / aws)

And it does not exist in other oracle kernels so this is not an environment issue for oracle cloud.

Since this is affecting the basic usage of docker / lxc, I will add kqa-blocker tag to highlight this.
