Server recipe fails due to undefined method `*' for nil:NilClass

My lxc container looks fine:

But the recipe has problems with the memory calculation:

Could you please run this command on your machine, and paste here the output?

free | grep Mem | awk '{print $2}'

This recipe has not been widely tested on Ubuntu.

I'm also having this issue. Here's what I get when I run the command:

vagrant@vagrant-ubuntu-trusty-64:~$ free | grep Mem | awk '{print $2}'

>> 2050004

My best guess is that the when 'linux' case isn't being triggered. That would make available_ram set to nil and return the error undefined method '*' for nil:NilClass?

@kigster Can you please follow up on this issue?
