когда я trye для перезапуска сервиса Bluetooth из терминального раскрывающегося сообщения об ошибке с этим содержанием

Connection to BlueZ failed
Bluez daemon is not running, blueman-manager cannot continue.
This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started.
