Playing with docker and the mailman bundler today in an attempt to get some images running, and I hit a point where I got this:

root@fd97a058ea83:~/mailman-bundler# apt-get install python3-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
python3-dev : Depends: libpython3-dev (= 3.4.0-0ubuntu2) but it is not going to be installed
Depends: python3.4-dev (>= 3.4.0-0~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

It was very non-obvious to me what was going on and google wasn't super helpful, so I'm posting in case someone else searches for the same "but it is not going to be installed" installed error message.

Turns out, what happened is that I needed to run apt-get update, and now it's happy.

Well, at least relative to that... buildout in mailman-bundler is complaining about numpy so I've still got some work to do!
