I came across an error while installing docker and running the default example on my new shiny ubuntu machine. Docker told me:
[~]$ sudo docker.io run -i -t ubuntu /bin/bash 2014/05/28 22:16:32 no such file or directory
And after switching to the latest, this:
[~]$ sudo docker run -i -t ubuntu /bin/bash 2014/05/28 22:22:41 set apparmor profile docker-default: no such file or directory
After a litte searching, and fiddling arround, I noticed that all of this had nothing to do with the real problem, ufw was getting in my way:
[~]$ sudo nano /etc/default/ufw
And automagically it worked. Documentation here , just didn't thought of this being the reason. Another good call to RTFM!
As always, hope it helps!
