error on installing OPEN SSL about docker-brew-ubuntu-core

[tianon]

In my experience, having RUN apt-get update by itself just causes cache issues down the road, so I always RUN apt-get update && apt-get install -y ... instead which causes a natural cache-bust when you need to change your installed packages, too.

I have hit the same issue.

Seems to work fine here: (so I'm going to need more information, but it sounds like you're missing apt-get update && ...)

My Dockerfile had RUN apt-get update as first line. I'll try again and report.

Same here was doing:

FROM ubuntu:14.04
RUN apt-get update
RUN apt-get install -y python-dev python-numpy python-matplotlib ipython-notebook python-pip

it was failing when trying to install python

Your method seems to work

[durdn]

@tianon Ah I missed the caching headache! Thanks!

[bfilippi]

Thanks for your quick turnaround
