Anthias supports Raspberry Pi OS Trixie
Anthias 2026.05.0 installs and runs on Raspberry Pi OS Trixie (Debian 13) as well as Bookworm, which people had asked for since Trixie came out in 2025. The README's compatibility list, which used to warn that Trixie wasn't supported, now names both for every board:
- Raspberry Pi 5, 4 and 3: 64-bit Trixie and Bookworm
- Raspberry Pi 2: 32-bit Trixie and Bookworm
- x86 PCs: 64-bit Trixie and Bookworm
Bullseye, and 32-bit Raspberry Pi OS on the Raspberry Pi 3 and 4, are no longer on the list.
The containers
Whatever the host runs, the containers are now built on Debian Trixie with Python 3.13. The Raspberry Pi images used to start from Balena's Bookworm-based images. On the Raspberry Pi 4, the viewer now uses the Qt 6 build of the WebView and plays video with mpv, the same as on the Raspberry Pi 5 and x86. The Raspberry Pi 2 and 3 stay on Qt 5 and VLC.
Raspberry Pi 1, Zero and the 32-bit Raspberry Pi 4
Images are built for the Raspberry Pi 2, 3, 4 (64-bit) and 5 and x86, and balenaOS disk images for the 4 Raspberry Pi boards. The installer stops on a Raspberry Pi 1 or any Zero with "Unsupported Raspberry Pi model", and installs the 64-bit images on every Raspberry Pi 4.
If you run Anthias on a Raspberry Pi 1, a Zero, or a Raspberry Pi 4 with 32-bit Raspberry Pi OS: there's no Anthias 2026.05.0 for the Raspberry Pi 1 or the Zero, so keep those on 0.20.5. Before you upgrade a Raspberry Pi 4, run
dpkg --print-architectureon it. If it printsarmhfrather thanarm64, reinstall it with 64-bit Raspberry Pi OS first.
