Since February 2025, Debian 13 (Trixie) and APT introduced the deb822 format for managing APT sources. This new format replaces the traditional /etc/apt/sources.list file with the more structured and readable /etc/apt/sources.list.d/debian.sources file.
This change was introduced by APT, starting with an update that enabled users to run:
apt modernize-sourcesThis command automatically converts the old sources.list format to the new deb822 format.
Caution Upgrading from Debian 12 to Debian 13 on machines with mdadm has intermittently failed for me; symptom is that grub EFI is not up to date and system boots into BIOS. Root cause under investigation; it might not be related to mdadm.
To start, read the official release notes.
If your install fits into "vanilla Debian plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Debian 13 "trixie" from Debian 12 "bookworm" can be helpful. 3rd-party repos are handled with a find command.
Note upgrade is only supported from Debian 12 to Debian 13. If you are on Debian 11, upgrade to Debian 12 first. Then once on Debian 12, you can upgrade to Debian 13.

The goal of this article is to explain how to install one or many Raspberry Pi 3 B+ devices connected with one to four Raspberry Pi Zero 1.3 devices each via USB OTG networking.
Each device - Pi and Zero - will be connected to the network 192.168.0.0/24. Each Zero will be connected via USB OTG to the Pi. That will establish a network between the two devices. On each Pi a network bridge will be configured to forward the traffic between the Pi ethernet port and the connected USB ports.
Their individual hostname/IP pattern will be:
10.lab | 192.168.0.10 (1st Pi)
20.lab | 192.168.0.20 (2nd Pi)
