[Discourse.ros.org] [Packaging and Release Management/Indigo] Docker : Error : Unable to communicate with master!

Gary Edwards via ros-users


I am following the simple [Docker tutorial](http://wiki.ros.org/docker/Tutorials/Docker) and coming across "ERROR: Unable to communicate with master!". Here's the output :

dparkar@dupin:~$ docker pull ros

Thanks for your question. However we ask that you please ask questions on http://answers.ros.org following our support guidelines: http://wiki.ros.org/Support



ROS Discourse is for news and general interest discussions. ROS Answers provides a forum which can be filtered by tags to make sure the relevant people can find and/or answer the question, and not overload everyone with hundreds of posts.



If youd like you can reply with a link to your answers.ros.org question, but in the future please start there.
