I'm trying sudo docker pull ubuntu on Docker 1.13.1 on Ubuntu 16.04.2 LTS and getting error:
Error response from daemon: manifest for ubuntu:latest not found
I don't use proxy so I have no idea where manifest got lost.
Well, it just started working 3 hours later without any intervention, so I make a conclusion that the problem was caused by Docker Hub incident.
This is caused by S3 outage, see docker- issue.
For some reason Docker haven't noticed yet, according to status.
Funny thing is that one can see other services unavailable like GitHub or Travis CI.
