Foreman » Packaging

Attempting to run foreman-installer on Ubuntu Xenial 16.04.1 results in package dependencies with ruby-concurrent.

[ERROR 2016-10-12T16:31:29 verbose]  ruby-dynflow : Depends: ruby-concurrent-ruby-edge (>= 0.2.0) but it is not going to be installed

Attempting to install the packages manually I get this error:

Apparently both ruby-concurrent and ruby-concurrent-ruby-edge are trying to provide the same things and stepping on each other, even though they're dependencies?
