Chistopher Penalver, it is hard to say as this is the first release
where I can no longer use Catalyst -- I have been using the the binary

Luis, in order to track your issue and hardware, it is helpful if you filed a

information running the following from a terminal:

I upgrade from 15.10 to 16.04.

Is there anything more I can do to help debug this? In my latest attempt
