"System Update Available" after already sideloaded Oreo I recently sideloaded Oreo onto my Nexus 5X, and everything went smoothly. However, today I received a "System Update Available" notification to "upgrade" to Android 8.0. I'm a bit confused; if I go through with this update, is it any different to what I sideloaded? And even if it is, is it better that I go through with it so that e.g. my phone believes that I have indeed upgraded?
As far as I can see it'll be a new build update, but simply prefaced with the android Oreo blurb.

I had exactly the same thing... And after updating compared the previous sideloaded build to the new one (even though it had been the sept 2017 security updates originally sideloaded) and the build number had bumped up.
