![Ubuntu 16.04 无法激活蓝牙/停止工作](https://linux22.com/image/902564/Ubuntu%2016.04%20%E6%97%A0%E6%B3%95%E6%BF%80%E6%B4%BB%E8%93%9D%E7%89%99%2F%E5%81%9C%E6%AD%A2%E5%B7%A5%E4%BD%9C.png)
我一直使用蓝牙,直到最近它停止工作,也就是说,我无法再通过系统设置中的界面激活它。我有一段时间没用它了,所以不确定是什么原因,可能是升级。
以下是一些输出:
$ sudo service bluetooth status

知道如何才能将它找回吗?
还添加以下输出:
