我的蓝牙设备找不到任何其他设备的信号 - Ubuntu 18.04？

我的蓝牙设备无法找到任何设备，尽管我已将其打开。我不知道，你能帮助我吗？

以下是一些信息：

rfkill：

$ sudo rfkill list
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

蓝牙控制：

$ bluetoothctl

在终端尝试

bluetoothctl

然后

power on

然后

scan on

应该全部连续完成，如果不行，请尝试安装蓝人图形用户界面用这个命令编程

sudo apt-get install blueman -y
