How to know what broken dependencies in F22 with dnf

[Sérgio Basto]

Hi, 
yum stops to work on F22 , first, at my point of view, just should be
marked as obsolete on F23 , is a rule , one release to change the
default , next release to obsolete it . 

Now, I need to find out what broken dependencies do we have and where ,
and dnf doesn't show it. How I do it now ? 

Thanks,
