#1: Installing applications from various types

This might not seem like such a bad idea at first. You are running Ubuntu so you know the package management system uses .deb packages. But there are a number of applications that you find only in source form. No big deal right? They install, they work. Why shouldn’t you? Simple, your package management system can’t keep track of what you have installed if it’s installed from source. So what happens when package A (that you installed from source) depends upon package B (that was installed from a .deb binary) and package B is upgraded from the update manager? Package A might still work or it might not. But if both package A and B are installed from .debs, the chances of them both working are far higher. Also, updating packages is much easier when all packages are from the same binary type.
