Problem with pulling docker base image from devhub-docker.cisco.com

[SteveZhang39274]

I tried to pull a base image with this instruction. But I always ran into following problem. Anyone knows what is the problem?

szhang-410-030:~/docker_test> sudo docker pull devhub-docker.cisco.com/iox-docker/ir800/base-rootfs
FATA[0000] Invalid repository name (ir800/base-rootfs), only [a-z0-9-_.] are allowed

Here are my docker version and Linux version:

szhang-410-030:~/docker_test> docker --version
Docker version 1.6.2, build 7c8fca2

szhang-410-030:~/docker_test> cat /etc/os-release
NAME="Ubuntu"
VERSION="14.04.5 LTS, Trusty Tahr"

Thanks

Steve

Hello Steve -- 

I'd start by upgrading your Docker version, as its all working fine here with a recent release and I seem to have a recollection this was an issue in the part.
