我在 ubuntu 20.04 focal 上安装了 virtualbox（版本 6.1.22 r144080（Qt5.12.8））。安装虚拟盒后，我在启动虚拟机时出现此错误。
Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver is either not loaded or not set up
correctly. Please try setting it up again by executing
'/sbin/vboxconfig'
as root.
如果您的系统已启用 EFI 安全启动，您可能还需要对内核模块（vboxdrv、vboxnetflt、vboxnetadp、vboxpci）进行签名，然后才能加载它们。请参阅 Linux 系统的文档以了解更多信息。
其中：suplibOsInit 内容：3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - 未安装支持驱动程序。在 Linux 上，open 返回 ENOENT。
我正在使用此代码来解决问题：
sudo /sbin/vboxconfig
并得到以下输出：
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is currently not set up to build kernel modules.
Please install the Linux kernel "header" files matching the current kernel
for adding new hardware support to the system.
The distribution packages containing the headers are probably:
linux-headers-generic linux-headers-4.4.0-104-generic

There were problems setting up VirtualBox. To re-start the set-up process, run
/sbin/vboxconfig
`as root. If your system is using EFI Secure Boot you may need to sign the
kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load
them. Please see your Linux system's documentation for more information.
我有两个操作系统。windows10 和带有 grub 的 ubuntu 20.04。我正在检查 bios 选项，安全机器人已被禁用。还检查了 windows，windows 中的启动选项没有问题。并且没有以 UEFI 样式安装。
我正在尝试安装
linux-headers-generic linux-headers-4.4.0-104-generic
但出现了这个错误：
E: Package 'linux-headers-4.4.0-104-generic' has no installation candidate
我该如何解决这个问题？

答案1
确保您的系统已完全更新，并且旧的、过时的内核不会妨碍您：
sudo apt update && sudo apt full-upgrade && sudo apt autoremove
如果没有报告错误，则继续安装vboxconfig似乎缺少的内容：
sudo apt install build-essential linux-kernel-headers
最后，此时应该能够正确运行脚本：
sudo /sbin/vboxconfig
