The root of the problem is that apt is not a packaging format. It's a big, working ecosystem solving many problems of installing software into a system. Ubuntu is not willing (nor able) to replicate this ecosystem, but they keep pretending that you can sacrifice basic usability for security and treat every application as a self-sufficient island. You can make it work for some, which are either simple or have been created that way (Firefox). But it's never going to work in the general case.
