can't build container, failed openjdk dependency

[blacksd]

Hi, I tried the instructions to build the container but the procedure stops for missing deps. Which is kind of strange, because in xential the packages are there https://launchpad.net/ubuntu/xenial/+package/openjdk-6-jre-headless

docker-unifi-controller git:(master) make
docker build -t="rednut/unifi-controller:latest" --rm --no-cache .

The latest ubuntu image is now 16.04 causing the SHA1 failures.

Changing FROM ubuntu to FROM ubuntu:trusty is one fix.
