This usually happens when you do non-standard things like try to change the desktop environment and then update to a new major version. If you pick a distro that is already close to what you need in the first place, this should not be as much of an issue.

It is possible to get it into such state, but on a good distro like Debian simply changing the desktop environment and updating to a new major version is not going to be one of those troublesome "non-standard" things :)
