Ever do a sudo apt update on your Raspberry Pi?
And you get this error message? It says
E: Release file for http://archive.raspberrypi.com/debian/dists/bookworm/InRelease is not valid yet (invalid for another 10h 37min 50s). Updates for this repository will not be applied. E: Release file for http://deb.debian.org/debian/dists/bookworm-updates/InRelease is not valid yet (invalid for another 12h 15min 47s). Updates for this repository will not be applied.
If you do
sudo hwclock -s
It will fix it. Apparently it’s to do with the hardware clock having drifted and I’m guessing this causes an error condition. Still, its an easy fix!
