Ruby fog gem causing server not to run: cannot load such file -- xmlrpc/client (LoadError)
As the title states, I'm trying to set up an Ubuntu 16.04 system for working on rails apps. When I comment out the fog gem, the server starts locally, and with the gem left in it produces the error message below. Googling doesn't seem to provide anything as I can't find anyone else with the same error as me, and I cannot simply remove the gem from the app as it's needed.
The full message is as below:

If anyone can tell me how to either download / install the xmlrpc client or work around the issue that would be appreciated.
Answer
So the problem is that starting in Ruby 2.4.0, the xmlrpc library that was before bundled with ruby has been extracted to a gem. So you must just add this to your gem file and bundle again.
gem 'xmlrpc'
