pull access denied repository does not exist or may require docker login

Question

I am using Laravel 4.2 with docker. I setup it on local. It worked without any problem but when I am trying to setup online using same procedure then I am getting error

Answer 1

Just make sure to write the docker name correctly!

In my case, I wrote (notice the extra 'u'):

FROM ubunutu:16.04

The correct docker name is:

FROM ubuntu:16.04
