Off-topic, but related to "trixie / sid" on RPi4 On a freshly written 64-bit raspberrypi os bookworm (Lite) image, replaced word "bookworm" by "trixie" in following two files: "/etc/apt/sources.list" and "/etc/apt/sources.list.d/raspi.list" . After above modifications, ran following commands: sudo apt update sudo apt full-upgrade sudo apt autoremove sudo apt autoclean sudo reboot The upgrade command took about half an hour to complete, and upgraded 470 packages. No issues during & after upgrade. Everything is OK.

Thanks @Igor for your prompt attention and help. Yes, you are right. The error messages I posted in my last post do NOT break anything, but these are very irritating.
