Cannot push new version tag

Docker Engine General
1

Hi, I want to tag existing image in my repository to have stable tag (so when I build and push new images, I would still be able to download and use last version of which I know that works).

I have this images:

[garret@jsedlak_ntb ~]$ docker images
REPOSITORY                         TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
docker.io/fedoraqa/openqa_webui    latest              8b161b6a3b8c        10 days ago         770.4 MB
docker.io/fedoraqa/openqa_worker   latest              f8ac962ec807        10 days ago         1.043 GB
docker.io/fedoraqa/openqa_data     latest              9088dfa73aa5        4 weeks ago         445 MB

I tag them with:

[garret@jsedlak_ntb ~]$ docker tag fedoraqa/openqa_webui fedoraqa/openqa_webui:stable
[garret@jsedlak_ntb ~]$ docker tag fedoraqa/openqa_worker fedoraqa/openqa_worker:stable
[garret@jsedlak_ntb ~]$ docker tag fedoraqa/openqa_data fedoraqa/openqa_data:stable

so now I have:

[garret@jsedlak_ntb ~]$ docker images
REPOSITORY                         TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
fedoraqa/openqa_webui              stable              8b161b6a3b8c        10 days ago         770.4 MB
docker.io/fedoraqa/openqa_webui    latest              8b161b6a3b8c        10 days ago         770.4 MB
docker.io/fedoraqa/openqa_worker   latest              f8ac962ec807        10 days ago         1.043 GB
fedoraqa/openqa_worker             stable              f8ac962ec807        10 days ago         1.043 GB
fedoraqa/openqa_data               stable              9088dfa73aa5        4 weeks ago         445 MB
docker.io/fedoraqa/openqa_data     latest              9088dfa73aa5        4 weeks ago         445 MB

But when I want to push it, it shows:

[garret@jsedlak_ntb ~]$ docker push fedoraqa/openqa_webui:stable

Do you really want to push to public registry? [Y/n]: Y
The push refers to a repository [docker.io/fedoraqa/openqa_webui] (len: 1)
FATA[0002] Error pushing to registry: Tag does not exist: stable

I have been looking into it and I still can’t figure out what am I doing wrong. I am running Fedora 22 and I have this version of docker:

[garret@jsedlak_ntb ~]$ docker version
