I know this is not a Qt question, but I hope there is someone for whom this question is a piece of cake to answer.
How do I set up a "private" deb repository and make N950's package manager knowledgeable about it. I do have some debian experiences from the early 2000-s and I know what is "apt/sources.list" but the way this system is configured on N950 looks unfamiliar to me and I would hope for a simple "add this line" advice here before I dive into the manuals (of course, I've done some googling by now, didn't help).
To be more specific, there is just one application I will be needing to update. I make it for a friend and I want him to be able to update it on his phone when I make changes. What are the two simple steps to make it "updateable", assuming I do have a webserver available where I could publish files via HTTP and I can ask my friend to modify his /etc/apt/sources.d or whatever.
