Docker on Ubuntu 14.04 - Could not resolve 'archive.ubuntu.com'

Hi,

I’ve having an issue with Docker 1.1.1 on my Ubuntu 14.04 VPS in the London zone.

I’m getting the following output when executing docker run --name="test" ubuntu:14.04 apt-get update,

Err http://archive.ubuntu.com trusty InRelease
  
Err http://archive.ubuntu.com trusty-updates InRelease
  
Err http://archive.ubuntu.com trusty-security InRelease

W: Some index files failed to download. They have been ignored, or old ones used instead.

I’ve done some Googling, but couldn’t find anything that was related to this specifically. /etc/resolv.conf contains the same contents as the parent VPS, which are,

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 2001:4860:4860::8844
nameserver 2001:4860:4860::8888
nameserver 209.244.0.3

Anyone have any ideas? Possibly IPv6 related as per https://lists.debian.org/deity/2014/05/msg00036.html?
