今天新版 Ubuntu 22.10 發佈，高高興興升級完成後，發現：1.Flameshot 異常；2.沒法連接 AirPods Pro2 耳機了；3.定製 ibus 的 gnome 插件不兼容(預料之中)。

藍牙耳機連不上的的時候，症狀爲 Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable：

1    [bluetooth]# connect C0:95:6D:C0:A3:92
2    Attempting to connect to C0:95:6D:C0:A3:92
3    Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable

這就是 linux 用戶的日常，搜索後確定大致原因爲，Ubuntu 22.10 桌面版本音頻服務從 PulseAudio 切換到 PipeWire, 導致的服務異常。

解決方法

    1. 安裝依賴包
    1  sudo apt install wireplumber libspa-0.2-bluetooth wireplumber-doc

依賴包解釋說明

  • WirePlumber is a modular session / policy manager for PipeWire

  • libspa-0.2-bluetooth libraries for the PipeWire multimedia server bluetooth plugins

    1. 重啓 wireplumber
    1systemctl --user restart wireplumber
    1. 重新連接 AirPods 耳機, 看最後返回 successful
     1➜  bluetoothctl
 2Agent registered
 3[bluetooth]# connect C0:95:6D:C0:A3:92
