The example on docker.com produces the following for me. I’m running Docker on Ubuntu 14.04 LTS.

Hi,

This error is just because the docker daemon cannot reach ubuntu apt repositories. Make sure your machine running docker daemon can reach internet.

Regards

Thanks. The machine can reach the Internet. I use apt repositories from it all the time. Maybe the demo needs to be run as sudo? No, that doesn’t fix the errors.

It appears that docker wasn’t able to access a DNS. The Ubuntu 14.04 LTS machine that I have docker installed on is using a dynamic IP number provided by a DHCP server on a LAN. I added the IP of the LAN’s router to the file /etc/default/docker. I suppose I could also provided the IP numbers of some DNS’s. In any case, I was then able to build the example, but I did receive:

debconf: (TERM is not set, so the dialog frontend is not usable.)

debconf: unable to initialize frontend: Readline
debconf: (This frontend requires a controlling tty.)

The example does seen to work, however. Thx!

I have the same issue with Ubuntu 15.10 running in a VM.

All I did to resolve was, vi /etc/resolve.conf
Add the DNS server entry into it.

'nameserver x.x.x.x`
