I am running fedora 31 and grabbed virtualbox from RPM fusion but I have not been able to find a way to get it working.
The error when starting a VM is:
The VirtualBox Linux kernel driver (vboxdrv) is probably not loaded.You may not have kernel driver installed for kernel that is runnig, if so you may do as root: dnf install akmod-VirtualBox kernel-devel-$(uname -r)If you installed VirtualBox packages and don't want reboot the system, you may need load the kernel driver, doing as root: akmods; systemctl restart systemd-modules-load.service
If your system has EFI Secure Boot enabled you may also 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.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT
I have attempted to install the package requested but it does not exist
$ sudo dnf install akmod-VirtualBox kernel-devel-$(uname -r)

Package akmod-VirtualBox-6.1.2-1.fc31.x86_64 is already installed.
No match for argument: kernel-devel-5.4.13-201.fc31.x86_64
Error: Unable to find a match: kernel-devel-5.4.13-201.fc31.x86_64
Has this package been renamed to something else or does it not exist anymore?
