Hi applesandsynths,
Can you please detail how you reinstalled mono? I was having issues with sonarr after the upgrade to OS 6.7.1 as well.
When I try to install mono I am getting the following error messages
The following packages have unmet dependencies:
mono-complete : Depends: mono-devel (= 5.0.0.100-0xamarin4+debian7b1) but it is not going to be installed
Depends: mono-4.0-service (= 5.0.0.100-0xamarin4+debian7b1) but it is not going to be installed
Depends: monodoc-manual (= 5.0.0.100-0xamarin4+debian7b1) but it is not going to be installed
