Thanks for the report. I saw it as well on every run. I wonder whether this might be some missing policy in /etc/dbus-1/system.d/org.neard.conf? Or other in service?

@Soyal7, do you have a /etc/dbus-1/system.d/bluetooth.conf file? Mine looks like this (Ubuntu 20.04 so you may have to tweak):

<!-- This configuration file specifies the required security policies
     for Bluetooth core daemon to work. -->

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"
 "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>

  <!-- ../system.conf have denied everything, so we just punch some holes -->

  <policy user="root">
    <allow own="org.bluez"/>
    <allow send_destination="org.bluez"/>
    <allow send_interface="org.bluez.Agent1"/>
    <allow send_interface="org.bluez.MediaEndpoint1"/>
    <allow send_interface="org.bluez.MediaPlayer1"/>
    <allow send_interface="org.bluez.Profile1"/>

@mgreeraz I do and it is identical to yours.
