Summary of the issue you are facing:
Extension of Nextcloud-AIO on a RaspberryPi 5 with ‘Context Chat Backend’
Following the Description in /settings/apps/installed/context_chat_backend
I plan to connect my Nextcloud-AIO on a RaspberryPi 5 to a local AI runnng on a Windows-PC (Ollama/CUDA).
The main feature I wanted to get was the Retrieval-Augmented Generation (RAG) for my Nextcloud documents.
Calling the AI prompt from Nextcloud Assistant worked (!) .
AppAPI is running but the installation of the ‘Context Chat Backend’ failed and failed.
( ‘Gesundheitsprüfung’ ) does never come to an end - or if it comes to an end the button (“Herunterladen und Aktivieren”) is active again.
The docker_aio - AIO Docker Socket Proxy is configured.
I tried multiple variants beside the attempts in the GUI.
In AppAPI I also had tried to ‘Add registry override mapping’ . This is set back to Daemon: AIO Docker Socket Proxy (docker_aio)
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS
f8286b95e7b9 Package context_chat_backend · GitHub “supervisord -c /etc…” 23 hours ago Restarting (255) 27 seconds ago
docker logs write many messages: exec /usr/bin/supervisord: exec format error
Is a scenario with a Nextcloud-AIO and a context_chat_backend and context_chat on the ARM -RaspberryPi and a remote AI provider in the same network a valid attempt?
Or must the backend run on the Windows-PC (x64/ Ollama/CUDA)?
Is a context_chat_backend for ARM available at all?
I also checked GitHub - nextcloud/context_chat_backend but I did not see an answer :-(.

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
