Ubuntu 22.04.4 LTS 热关机后蓝牙不工作

我的 Ubuntu 22.04.4 LTS 发生热关机。重启后我发现蓝牙无法正常工作。出现此问题之前,我从 Ubuntu 软件安装了蓝牙管理器,但后来它变得无法使用。

根据不同来源的建议,我删除了上面提到的蓝牙管理器,安装了 BlueZ 并卸载。然后安装了blueman,但没有成功。

我进行了一些故障排除,但不知道我在做什么以及为什么这样做。以下是这些操作的一些结果:

  • 运行blueman-manager返回了如下图所示的错误:

    blueman-manager 错误

添加 USB 蓝牙适配器。得到以下结果。ashoke@Dell-3470:~$ 蓝牙 蓝牙 = 开启

删除上述适配器得到此 ashoke@Dell-3470:~$ 蓝牙 蓝牙 = 无(无设备)

  • 正在运行sudo systemctl start bluetooth返回:

    Failed to start bluetooth.service: Unit bluetooth.service failed to load properly, please adjust/correct and reload service manager: File exists
    See system logs and 'systemctl status bluetooth.service' for details.
    
  • 正在运行sudo systemctl status bluetooth.service返回:
