Oh, found the cause.https://www.raspberrypi.org/documentation/raspbian/applications/rpi-update.md rpi-update is a command line application that will update your Raspberry Pi OS kernel and VideoCore firmware to the latest pre-release versions. WARNING: Pre-release versions of software are not guaranteed to work. You should not use rpi-update on any system unless recommended to do so by a Raspberry Pi engineer. It may leave your system unreliable or even completely broken. It should not be used as part of any regular update process.
Side question: I think that I have only used this once, with no adverse effects. I usually use 'sudo apt-get update'. Is this different?
