Hello, guys!

Sorry if I will interrupt anyone with a repeatedly asked question, but I was not able to find a solution on Fedora based Linux system, and I hope that I will find one here.

So basically, yesterday I did sudo yum -y update, and today I was receiving an error that my Kernel is not installed.

I received this error after I tried to open my VM:

"VirtualBox Error : 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

where: sublib0sInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

They recommend me to use this command: /sbin/vboxconfig to fix the problem, after I entered this command as root, I received an error:

vboxdrv.sh failed: Look at /var/log/vbox-setup.log to find out what went wrong.

I tried this method:

Get your version kernel:

$ uname -r

Then find the corresponding kmod-VirtualBox-* package:

$ yum search kmod-VirtualBox

and install it:

$ yum install kmod-VirtualBox-#### appropriate version from list in previous step

Finally, run:

$ /etc/sysconfig/modules/VirtualBox.modules

This is what I received:

[root@local ~]# uname -r
5.4.17-200.fc31.x86_64
[root@local ~]# yum search kmod-VirtualBox

No matches found.
[root@local ~]# /etc/sysconfig/modules/VirtualBox.modules
-bash: /etc/sysconfig/modules/VirtualBox.modules: No such file or directory

I tried other method:

1. yum install dkms binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel

2. Then reboot and try: sudo /etc/init.d/vboxdrv setup

3. again. If that doesn't work, try: sudo modprobe vboxdrv

4. then try the setup command again.

This is what i GET. and that Pidgin repo is bugged somehow, tried to reach a method how to remove it, but I was not able to do it:

1.
[root@localhost ~]# yum install dkms binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (5.4.17-200.fc31.x86_64) or it failed to

sudo /sbin/vboxconfig

You will not be able to start VMs until this problem is fixed.

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.

[root@local ~]# etc/init.d/vboxdrv setup
-bash: etc/init.d/vboxdrv: No such file or directory

Hope to find a solution from you, guys! Sorry for your time.... I find many solutions online, but most of them was for ubuntu, so I am a bit stuck here. Got an imporant files on my VM, so I can't just reinstall it...

What was in the file /var/log/vbox-setup.log ?

I haven't attempted VBox on Fedora in ages, but that is just the kernel module not being rebuilt. Simply boot back to the prior kernel should get everything going.
Fixing the issue depends on how it was installed - these days a simple dnf update should resolve it, presuming the virtualbox repo is in place. The kmod/dkms should only be necessary if you got it from rpmfusion, as used to be the case.
