content: This is a somewhat widespread problem, unfortunately. In order to update this Galaxy Note 4 from Android 5.1.1, I apparently need to install like 4 updates in a row, depending on which of them is already installed. Its fucking rediculous. And this goes for Ubuntu Linux too, last I heard. I.e. if you're on 15.04 and you want to go to 16.10, you need to first upgrade to 15.10, then 16.04 and then finally 16.10. The exception here is that you can supposedly jump from one LTS directly to the next.
