    Yes, if you follow the licensing terms, "Open Source" and all that. – waltinator Oct 24 '18 at 20:15

Yes, but... you must abide to the licenses in the initial Ubuntu source code. Many of these licenses require that you distribute the source code of your modifications to the code. This means that folks (or even competitors) can just take your source code and use it (or even sell it).

In practice, you cannot make much money selling software that derives from Open Source code. What you can do, if your OS has some merit, is sell support. This is for instance the "business model" or RedHat's RHEL, and they make money from it (despite the existence of CentOS, which is mostly RHEL-made-free-again).
