Problem running hello-world


I am trying to get started with docker using following tutorial:
However I am stuck at the very beginning, since running:

sudo docker run hello-world

produces the following error.

Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get dial tcp: lookup on read udp> i/o timeout.

I hope I’ll not mislead someone; but guess that the problem is in networking: after I install docker I cannot ping the internet any more, after I uninstall docker, the internet gets back.

Can someone please help with some suggestion on how to proceed?
Docker (v= 17.03.1-ce) is installed under Ubuntu (v= 16.04.2 LTS) running inside of Virtual Box (v= 5.1.22 r115126 (Qt5.6.2)) on Windows 10.

Thank you,

Out admin resolved the issue…
Problem was that docker default IP address ( was exactly the same as our network range.
