"docker pull ubuntu " doesn't work

I'm trying to follow the docker hello world example but when I enter the following command and my password nothing happens:

$ sudo docker pull ubuntu
[sudo] password for mike:

It literally stays like that for ages. I've tried on two different Ubuntu 12.04 desktops and it's always the same.

UPDATE: What is actually going on is that a new window is opened which is extremely small, when I expand it the window has no content. if I close the window I get the message:

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 32 requests (32 known processed) with 0 events remaining.

UPDATE 2: Turns out this isn't a real problem, the program I was running was in fact not docker. - A word of warning, sudo apt-get install docker on Ubuntu installs another program called docker, not the virtualization tool.

On debian and ubuntu the package as well as the executable/command is called docker.io.

You should better run

$ sudo docker.io pull ubuntu

Btw.: docker is (also) a “system tray for KDE3/GNOME2 docklet applications”.

I reckon this is solved if you install docker correctly as described in your other issue Docker opens up a tiny new window that does nothing

That's weird! To decompose between a possible sudo issue and a docker issue, can you try the following:

  • first, run sudo ls; this should ask for your password, and if successful, it will just list the current directory; but in the process, it will enable your session to use further sudo commands without typing your passwords again;
  • then, run sudo docker ps; this shouldn't ask for your password, and if successful, this should output one line of header, and return to the prompt;
  • finally, try sudo docker pull ubuntu and see what happens.
