    I started to receive these mails in one of my servers with Debian 8 but I don´t have the line you told in step 2:


    root@xxx:/# grep -r graf /etc/apt/

    /etc/apt/sources.list.d/plesk-ext-grafana.list:deb stable main

    Coincidencia en el fichero binario /etc/apt/trusted.gpg

    Also in /var/log/grafana/grafana.log I can see:

    logger=ngalert.scheduler rule_uid=avOeDO37k org_id=1 version=1 attempt=0 now=2023-06-23T00:03:00+02:00 t=2023-06-23T00:03:00.000941868+02:00 level=error msg="Failed to evaluate rule" error="[plugin.notRegistered] plugin not registered" duration=0s
