Boot Linux or OpenBSD on the PowerBook G4 (PowerPC/ppc32)

Creating the USB sticks

Use an older USB 2.0 stick, newer ones will most certainly not work.

sudo dd if=debian-11.0.0-powerpc-NETINST-1.iso of=/dev/sda1 status=progress # Or use GNOME Disks, Etcher etc.
sync

You need SSH access, a personal Matrix account, a bot Matrix account, and a server (if self-hosting via Ollama, at least 32 GB of RAM)

1. Clean Up Old Matrix Sessions

Sign into your bot account in Element, go to Settings → Sessions, and delete any stale sessions to avoid E2EE key conflicts.

2. Create the Service User

SSH into the server and create a dedicated nanobot user with passwordless sudo and lingering enabled (so its systemd user services survive logout):

Nextcloud High Performance Backend and Recording Setup

Commercial hosted providers (I recommend using these instead of hosting it yourself, esp. if you're setting this up for someone else):

• https://rcasys.com/en/services/hosting/managed-nextcloud-talk-videoconferencing
• https://www.spreed.eu/contact-nextcloud-talk-high-performance-backend/

This pad is heavily based on https://arnowelzel.de/en/nextcloud-talk-high-performance-backend-with-docker - it's probably best to check if there were any changes in that article before you proceede here.
