Question

I am getting error on ubuntu 16.04

\"ERROR: Couldn\'t connect to Docker daemon - you might need to run docker- machine start default. \"

Answer 1

I noticed that I got this error after installing docker-compose. Trying to runsudo docker-compose build gave me the error --

ERROR: Couldn't connect to Docker daemon. You might need to install Docker

I solved this by installing docker-ce (Ubuntu 16.04 and 18.04). Everything worked as expected thereafter
