F29 VirtualBox - vboxdrv failed

edit

Hello,

I'm trying to run the last version of VirtualBox 6.0.2 on my Fedora 29, however I'm getting error regarding the Kernel modules.

Failed to create a host network interface.

VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory.

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: HostNetworkInterfaceWrap
Interface: IHostNetworkInterface {455f8c45-44a0-a470-ba20-27890b96dba9}

I've the Kernel-devel dkms kernel-headers installed to my kernel

Package kernel-devel-4.19.15-300.fc29.x86_64 is already installed.
Package dkms-2.6.1-2.fc29.noarch is already installed.
Package kernel-headers-4.19.15-300.fc29.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!

When I try to run the manually i get error

1:VirtualBox-6.0-6.0.2_128162_fedor################################# [100%]

Creating group 'vboxusers'. VM users must be member of that group!

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.

How i solved?

• First disable SELinux on /etc/selinux/config set SELINUX=DISABLED

• Then after check deeply dmesg -w I found that it was lockdown because the module is not signed also security boot was enabled so i needed to use mokutil to disable it

• sudo mokutil --disable-validation

• reboot follow the steps and disable the secure boot

• then run agan /sbin/vboxconfig setup

EDIT 1#:

When running sudo '/sbin/vboxconfig' or from a Root terminal i get the following message: vboxdrv.sh: Stopping VirtualBox services. vboxdrv.sh: Starting VirtualBox services. vboxdrv.sh: Building VirtualBox kernel modules. vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.
