  6. 我的蓝牙 Logitech M585 工作正常：

    Device E1:B5:43:77:D0:97 M585/M590

  7. tail -f /var/log/syslog尝试再次连接时的输出bluetoothctl：

    Jan  4 16:46:43 bonavel bluetoothd[887]: 04:5D:4B:96:D5:65: error updating services: Host is down (112)

  8. 输出pactl list | grep -i bluetooth

    Name: module-bluetooth-policy
    module.description = "Policy module to make using bluetooth devices out-of-the-box easier"
Name: module-bluetooth-discover
    module.description = "Detect available Bluetooth daemon and load the corresponding discovery module"
    module.description = "Detect available BlueZ 5 Bluetooth audio devices and load BlueZ 5 Bluetooth audio drivers"

  9. 应用这解决方案，但仍然不起作用。

  10. 应用这解决方案，现在我可以配对和连接，但它无法重现声音，尽管它很快就断开了连接。

  11. 第 10 项之后的输出bluetoothctl。

  1. 我对耳机进行了工厂修复，如下所示这说明。然后我就可以配对并连接它了。但是当我播放一些音频时，感觉有很多干扰，只有一些随机的非常尖锐的噪音，我甚至无法理解正在播放的内容。然后我能够断开连接并再次连接，但现在根本没有播放任何声音。然后大约 1 分钟后，耳机失去了连接。

  2. 在软件更新设置中它看起来像这样： 软件更新设置

我已经搜索了 2 个多小时并应用了找到的所有可能的解决方案，但没有一个能解决我的问题，所以我从头开始重新安装了 Ubuntu 18.04.3。

答案1

问题是其中一个天线Intel Corporation Wireless-AC 9560断开了。我打开电脑，连接天线，蓝牙工作正常，Wifi 信号更好。
