Docker & Trixie

Docker is not yet officially supported so Alex and Baden will remain on Bookworm for the time being

However - Cisco and Davros are my test servers so I will be giving them a spin on Trixie and see how we go. A guide is here as everyone else is giving them a spin.

How to upgrade to Trixie

#!/bin/bash
# Debian 12 → Debian 13 Upgrade Script
# Reference: https://linuxconfig.org/how-to-upgrade-debian-to-latest-version

echo "=== Debian Upgrade Script: Bookworm → Trixie ==="

echo "Upgrade complete. Please reboot the system..."
echo "Reinsall Docker after reboot using your preferred method."
echo "=== End of Upgrade Script ==="

The Proxmox Community appear to be waiting as well.

I will bring up my two main servers and leave the others although I might spin up a Debian Trixy LXC and see what gives. A Debian 12 seems to break at the moment, so I will need to look at that.
