Problem scenario
You have Docker installed. When running "docker ps" you get this error: "An error occurred trying to connect: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json: read unix @->/var/run/docker.sock: read: connection reset by peer"
How do you fix this error so you can use Docker?
Solution
Just because Docker was installed does not mean that the kernel of your OS is supported. Docker may not work despite being installed. To find out if you kernel is supported, try this command: docker daemon
