Thanks very much! I'll kick off a build now and deploy it when it's ready.

@arnocandel The build hit an error with a missing public key when trying to install a dependency of python-software-properties. It looks like the sort of thing we ran into when installing MXNet a while ago. We cobbled together some patches for it in the MXNet section, so I'm going to try moving the h2o install after that and see how it goes.

The missing public key was fixed by re-using the python-software-properties install from the MXNet section. I'm removing software-properties-common because it seems to want to stomp over our Python installation (downgrading it to 3.4). I got a 404 on the oracle-java7-installer install last time, but I'll see how it goes on the next iteration.

I'm afraid we've hit the wall on the Java7 install. For some reason apt-get is looking in a .../wheezy/... location on the PPA, where I would have expected .../trusty/.... Here are the relevant lines of the build log:

I guess the answer might be to tinker with the apt-get configuration files, though I'll have to refresh my memory of how to do that. @arnocandel Do you know a solution off the top of your head? No worries if not; I'm out of the office tomorrow but I can get back to this next week.

@arnocandel Just tried the build again — same error. Looks like some apt-get configuration changes will be needed.

sudo apt-get update
sudo apt-get install oracle-java7-installer

Can we validate what this image really is

FROM continuumio/anaconda3:latest

it is possible the ubuntu ppa that is called there is not able to identify the release

it appears to be pure debian and not ubuntu trusty

@jgambera Oh wow, that's so weird — inside the container, uname -a reports Ubuntu 14.04. I didn't think to check what the base image was. Their anaconda3 image got rebuilt only a month ago, just before we last rebuilt kaggle/python.

@arnocandel @jgambera Thanks for your help with this one. The rebuild of our container was briefly derailed by a couple of other packages, but we're back in action now. We've now deployed the version with your changes in it.
