Making a .deb isn't as simple as it might seem. If you want to use shared libraries, especially so. Which version of Ubuntu/Debian/Mint/... whatever are you targetting? You can tools like FPM[1] (which is awesome btw, used it for some great hacks in the past), but that won't make you .debs that are necessarily done to the debian guidelines but usable.
There are a load os SaaS companies that do that allow you to make multiple targets though, so perhaps some integrations there would work.
