docker - Docker:HTTP代码403，同时上传元数据: “invalid character ' <' looking for beginning of value”

Question

当我尝试将Docker镜像推送到Docker集线器时:

docker push nickname/sokia-parser:latest

然后我从docker收到此错误:

The push refers to a repository [docker.io/nickname/sokia-parser] (len: 1)
Sending image list
Pushing repository docker.io/nickname/sokia-parser (1 tags)
843e2bded498: Pushing 
HTTP code 403 while uploading metadata: "invalid character '<' looking for beginning of value"

镜像的Dockerfile:

FROM python:3.4-onbuild

COPY . /usr/src/app

CMD ["./run.py"]

Docker版本是 1.8.2, build 0a8c2e3
请告诉我，哪里有问题？

Answer 1

尝试首先在注册表中删除镜像，然后再次推送。
