I'm planning on publishing a commercial (paid) application to Software Center and I've seen that during the process of submiting the app I have to upload a .deb package. I'd like to know if there is any way to submit updates to my certain application once it is already in Software Center. As far as I know apps from the Software Center are all in a ppa and that's how they get the updates, but in my case, there would be no ppa (correct me if I'm wrong)
Thanks
