Error pushing to registry: Head https://registry-1.docker.io/v2/xxx

Docker Hub
#1

HI,

I am not able to understand what is wrong with docker push. I am trying to push 2 images, one of them took at least 20 retries to get pushed, the other one, I have tried at least 50 times, everytime I get different error.
Here are the logs:

#docker push pensu/ppc64le-rails

How can a layer be present in one iteration and push fails in another iteration? Please make the messages clearer. And please look into it, this is very frustrating.

I am using docker 1.6.2.

I’ve been suffering this problem for a long time, it takes hundreds of retries to get through… and nobody seems to know what is going on. I posted similar question here: Can’t push image into the hub
