ksync: Cannot connect to the Docker daemon

Both ksync init and ksync doctor fail with the following error: rpc error: code = Unknown desc = Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

However, docker ps works, I can connect Docker containers to the Docker host by mounting /var/run/docker.sock, and the current user is in the docker group.

I’ve installed ksync using the gimme.sh script.
