docker build fails

[sronsiek]

I'm on a Mint host:

`Linux xxxx 3.19.0-18-generic #18~14.04.1-Ubuntu SMP Wed May 20 09:38:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux``

I placed the content provided here into Dockerfile & ran 'docker build .' in the same dir. The build fails when the nginx package tries to adduser - see output below.

Any suggestions??
