how to resolve libjson-ruby and ruby-json package conflict?

Asked by Ivan Storck on 2011-10-26

I am trying to install chef (client) on my ubuntu server but I am getting an error from aptitude that I would love some help understanding. I have searched on Google and Ubuntu forums for the answer but I did not see anything relevant yet.

It seems like aptitude thinks I need both libsjon-ruby and also ruby-json but they seem to conflict.
