在 Fedora 30 中，我为 VirtualBox 签署了内核模块（例如这里或者这里)。对每个文件执行 modprobe 后，我确认它们已加载，然后启动 vboxconfig。但是失败了，我找不到原因。
所有命令均以 root 身份运行。
# lsmod | grep vbox
vboxpci 28672 0
vboxnetflt 32768 0
vboxnetadp 28672 0
vboxdrv 499712 3 vboxpci,vboxnetadp,vboxnetflt
# /sbin/vboxconfig
MY_PATH="/usr/lib/virtualbox"
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: You must sign these kernel modules before using VirtualBox:
vboxdrv vboxnetflt vboxnetadp vboxpci
See the documenatation for your Linux distribution..
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.
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.
