Ubuntu 22.10连接蓝牙耳机报错br-connection-profile-unavailable解决方法

今天新版Ubuntu 22.10发布，高高兴兴升级完成后，发现：1.Flameshot异常；2.没法连接AirPods Pro2 耳机了；3.定制ibus的gnome 插件不兼容(预料之中)。

蓝牙耳机连不上的的时候，症状为 Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable：

[bluetooth]# connect C0:95:6D:C0:A3:92

这就是linux用户的日常，搜索后确定大致原因为，Ubuntu 22.10桌面版本音频服务从PulseAudio切换到PipeWire, 导致的服务异常。

解决方法

• 1. 安装依赖包

     sudo apt install wireplumber libspa-0.2-bluetooth wireplumber-doc

  依赖包解释说明

  • WirePlumber is a modular session / policy manager for PipeWire
  • libspa-0.2-bluetooth: libraries for the PipeWire multimedia server - bluetooth plugins

• 2. 重启 wireplumber

     systemctl --user restart wireplumber

• 3. 重新连接AirPods耳机, 看最后返回successful
