Resolution

  • NetworkManager は、アプリケーション間で DBUS 通信を使用します。このエラーは、DBUS 通信において接続先と送受信できないことを示しています。

    たとえば、「Org.freedesktop.NetworkManager.sleep-wake」は、polkitd デーモンがアプリケーションに渡すポリシー属性です。NetworkManager の接続先は polkitd デーモンです。

    システムの起動時とシャットダウン中にこのエラーが発生しました。NetworkManager の開始時にpolkitd の開始と終了が発生しているようです。
    その場合は、このエラーを無視しても問題はありません。

    稼働時にこの問題が発生したら、以下のコマンドを実行して polkit サービスを再起動してください。

    # systemctl restart polkit

  • polkitd が停止した場合は Getting "polkitd general protection error:0 in libmozjs-17.0.so" on Red Hat Enterprise Linux 7 を参照してください。
