What is up with the different repositories and URLs?

Question

I've got 2 rpis running bullseye, one recently installed and one image from a couple of months ago. The sources.list file changed dramatically.

My old installation:

# sources.list
deb http://raspbian.raspberrypi.org/raspbian bullseye main contrib non-free firmware rpi
# raspi.list
deb http://archive.raspverrypi.org/debian/ bullseye main

The other one:

# sources.list
deb http://deb.debian.org/debian bullseye main contrib non-free
deb http://security.debian.org/debian-security bullseye-security main contrib non-free
deb http://deb.debian.org/debian bullseye-updates main contrib non-free
# raspi.list
deb http://archive.raspberrypi.org/debian/ bullseye main

I'm curious what the different repositories are and if my older rpi is missing some repositories. Also what repositories are interchangable and is there any mirror to the http://archive.raspberrypi.org/debian/ repo?

Answer 1

Presumably you have installed Raspberry Pi OS 64bit on the newer Pi.

This uses the standard Debian ARM64 repository not the Raspbian.

The firmware is still provided by Raspberry Pi Ltd. and the source is the same for 32/64 bit

deb http://archive.raspberrypi.org/debian/ bullseye main
