The Prosody AppImage included in the plugin will only work on x86_64 and arm64 CPU. It is not compatible with other CPU architectures.
To use the plugin, you will have to manually install Prosody on your server (see below).
Note: the plugin requires Prosody >= 0.12.0. If you are using an older version, Chat Federation could be broken, and it could have some unexpected behaviour.
Once it is done, you have to check Use system Prosody in the plugin
settings.
For standard installation, you just have to install the official prosody
package for your linux distribution.
For example, on Debian/Ubuntu:
sudo apt install prosody
You can then disable the service that starts automatically when you install Prosody (the plugin will launch a Prosody process, there is no need for the service to run). For example, on Debian/Ubuntu (and other Systemd based linux distributions):
sudo systemctl disable prosody && sudo systemctl stop prosody
Warning: do not disable Prosody if it is used for another service on your server, like for example Jitsi.
You will have to generate a Peertube image that includes Prosody in the same container that Peertube. I know this is not the standard way to do this with Docker, but keep in mind it is a temporary workaround.
To generate and use such an image, please refer to the Docker documentation. The Docker file to generate the image should be:
FROM chocobozzz/peertube:production-bullseye
RUN apt -y update && apt install -y prosody && apt -y clean
You have to disable metronome (the XMPP server provided by Yunohost), and
install prosody.
This is already done by the Yunohost Peertube application, as it was required for the plugin before the v6.0.0.
But it may be removed in a near feature (to avoid drawbacks of this method). I have to discuss with Yunohost team, to decide how we can do to minimize drawbacks, and maximize compatibility.
