my solution is to edit the polkit file for kodi and disable the Subject.user check:
for Arch Linux Arm you edit this file: /usr/share/polkit-1/rules.d/10-kodi.rules

xml:


polkit.addRule(function(action, subject) {

//    if (subject.user == "kodi") {

        polkit.log("action=" + action);

        polkit.log("subject=" + subject);

        if (action.id.indexOf("org.freedesktop.login1.") == 0) {

            return polkit.Result.YES;

        }

        if (action.id.indexOf("org.freedesktop.udisks.") == 0) {

            return polkit.Result.YES;

        }

        if (action.id.indexOf("org.freedesktop.upower.") == 0) {

            return polkit.Result.YES;

        }

//    }

});
