Thanks for the effort to help me solve this it is appreciated.
I'm running OMV 2.1.7
I ran all of the above commands once more and tried to install again.
This is what I get - http://pastebin.com/kB2g64X1
Same error still.
Code
openmediavault-sonarr : Depends: libmono-cil-dev (>= 3.10) but 2.10.8.1-8+deb7u1 is to be installed
Thanks again.
