Kubuntu 没有可用的蓝牙适配器

笔记：此问题是由于最近更新了联发科驱动程序而引起的。如果您在使用联发科设备时遇到类似问题，以下答案可能会有所帮助。

我正在使用kubuntu 21.10。我的 Wi-Fi 工作正常。但我无法使用蓝牙。
我正在使用双启动（Linux + Windows）。我可以在 Windows 中使用蓝牙。请参阅我的截屏的。

注意：我已经从 BIOS 选项中禁用了安全启动。

安装支持您的设备的最新稳定内核。

  1. 安装自动检查并安装最新内核的 bash 脚本：

    wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/ubuntu-mainline-kernel.sh
sudo install ubuntu-mainline-kernel.sh /usr/local/bin/

  2. 运行 bash 脚本：

    sudo ubuntu-mainline-kernel.sh -c

  3. 安装最新的稳定内核：

    sudo ubuntu-mainline-kernel.sh -i

  4. 按下Y以接受安装。

  5. 重新启动以启动到最新内核：

    sudo reboot

您也可以使用 deb 文件安装驱动程序（更好、更稳定）：

  1. 更新存储库：

    sudo apt update

  2. 下载 deb 文件：

     wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-image-unsigned-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb
 wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-modules-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb

  3. 使文件可执行：

    sudo chmod +x *.deb

  4. 安装文件：

    sudo dpkg -i *.deb

  5. 满足依赖关系：

    sudo apt -f install

  6. 安装内核头文件（可选）

    sudo apt install linux-headers-generic

  7. 重新启动以启动到较新的内核：

    sudo reboot
