Description of my issue

When installing matrix_signal the installer gives many warnings and fails. I have tried on a few fresh yunohost installs and it’s always the same result. Here are a few log lines when the install process starts to hit problems

You defined the same matrix user as user and admin of the bridge, which results in a duplicate key in the config.yaml file. Just leave defaults values at install and modify them from the config panel afterwards.

found duplicate key "@mack:maindomain.tld" with value "admin" (original value: "user")

Deploying with defaults and editing later did the trick. Thank you
