can't push or pull to a docker repo `Repository not found`

Question

I am new to docker. created a public repo under my account link to repo

I am able to pull other public repos like redis and debian:

docker ps                                    ✱
CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS              PORTS               NAMES
40416ad4c715        debian:latest       "/bin/sh -c 'while t   6 minutes ago       Up 6 minutes                            dal_server

but when trying to pull from my repo i get an error:

docker pull opmaster/basic_server            ✱
Pulling repository opmaster/basic_server
FATA[0009] Repository not found

docker push opmaster/basic_server            ✱
The push refers to a repository [opmaster/basic_server] (len: 0)
FATA[0000] Repository does not exist: opmaster/basic_server

>> docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

debian              latest              41b730702607        10 days ago         125.1 MB
hello-world         latest              91c95931e552        3 weeks ago         910 B

>> docker tag 41b730702607 opmaster/basic_server:devel
>> docker push opmaster/basic_server

docker push can get be little long from my short experience, so i stopped it with ctrl-c, did boot2docker restart and started again with the docker push opmaster/basic_server

if someone knows a better way, i'm open to suggestions.
