I have some code that I developed and built into a deb package. However, unlike other packages when you double click it in Ubuntu the licence field shows up as "Unknown". Instead I want it to say "Proprietary" like others.
I couldn't find anything in the control file definition that adds it. And looking at other packages such as the nvidia ones that do say "Proprietary", I can't see anything in there that would add it.
How do I set a licence?
