我对 ubuntu 还很陌生，正在慢慢适应它，但我似乎经常遇到蓝牙连接问题。它一直运行良好，直到我完成了建议的更新，现在我无法连接到蓝牙扬声器。
我已经跑了sudo service bluetooth status：
● bluetooth.service - Bluetooth service
Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset
Active: active (running) since Thu 2018-01-11 23:33:41 GMT; 13min ago

知道该怎么办吗？Sap 驱动程序或 RFCOMM 服务器似乎有问题，它们是什么？抱歉，我对 Linux 还很陌生
