any ideas?

@JackMc @deniszgonjanin ?

@husker couple of ideas:

• Cisco VPN messes with Virtualbox networking. Since docker works with virtualbox on OSx, this causes docker to die. See: docker-machine env xxx hangs forever docker/machine#1500
• When switching wifi networks, Virtualbox networking will sometimes die inexplicably. Restarting that virtual machine works well. Try docker-machine stop dev & docker-machine start dev. Replace dev with the name of your VBox machine used for docker.

thanks @deniszgonjanin - tried those, unfortunately i'm still having the same issue. i think i'll give it a try on linux - what flavour of linux do you recommend as most compatible? centos?

[deniszgonjanin]

Ubuntu.

By the way, you seem to be getting the error with datacats open. That just launches a browser at whatever address your CKAN is. Try opening it manually. Run datacats info to find out the url where it's running.

it seems i get the same error trying to run any datacats commands.

Can you make sure docker is indeed working? docker ps should return a list of running containers. Fixing docker would likely solve your problems
