从17.04升级到17.10后失去了蓝牙function

一天前或之前我从17.04更新到17.10，我能够通过蓝牙连接我的电脑和耳机。 现在我做不到。 我想也许我需要从软件管理器安装蓝牙管理器和蓝牙适配器，但这没有帮助。 有人可以建议我可以通过终端使用的一些代码重新安装蓝牙驱动程序或任何不工作的所以我可以回到我的计算机上使用蓝牙function吗？ 在设置上，蓝牙，它说插入加密狗现在使用蓝牙。 之前没有说过这个。

Answer 1

我昨天将Kubuntu从17.04升级到了17.10。

对我来说大致相同的问题，即使我的蓝牙服务正在运行，我也无法再连接我的蓝牙音箱（RYGHT TANK）。

这是我的sudo service bluetooth status和dmesg | grep -i blue dmesg | grep -i blue结果：

尝试连接后消息的打印屏幕： 连接失败

任何的想法？

编辑（11/05）（安装了pulseaudio-module-bluetooth之后）：

编辑（11/05得到它！）：我最终得到了一个解决方案：

 sudo apt install kmix reboot 

然后

 sudo apt install pulseaudio-module-bluetooth reboot pactl load-module module-bluetooth-discover 

（最后一个命令可能失败）

然后删除所有已保存的蓝牙设备并再次配对。

不要忘记将蓝牙设备设置在音频配置列表的顶部：
