蓝牙错误：dbus.exceptions.DBusException：org.freedesktop.DBus.Error.UnknownObject：

tag-icon • tag-icon usb bluetooth hardware dmesg
蓝牙错误：dbus.exceptions.DBusException：org.freedesktop.DBus.Error.UnknownObject：

使用 ubuntu 16.04 后，我意外地从蓝牙管理器设备列表中删除了蓝牙耳机设备，该设备要么在蓝牙搜索中不再可见，要么在搜索期间在设备列表中显示几秒钟，然后消失。我现在无法使用我的蓝牙耳机。

如果我从终端运行 blueman-applet，我会在搜索过程中看到异常，然后设备被删除。
