This says that activating the contribdnn flag also needs the contrib flag to be activated. Hard to give any direct advice without knowing what you are trying to do. On my computers I don't install opencv, so the easiest solution if you don't need it is to remove the opencv flag from any packages you have installed. Regards, Arve
