VirtualBox Guest Additions for Linux Guest with kernel 5.0.5

Question

I'm trying to setup VirtualBox Additions for enabling shared folders between host and guest machine. The configuration is:

Host  : Windows 10 x64
Guest : Fedora Server 29.1.2 x64 [with updates up to kernel 5.0.5-200.fc29.x86-64]
VirtualBox version on host machine : 6.0.4

Instructions I'm following are:

sudo dnf -y upgrade
sudo dnf -y install gcc kernel-devel kernel-headers dkms make bzip2 perl kernel-$(uname -r) elfutils-libelf-devel libell binutils patch libgomp glibc-headers glibc-devel  automake
sudo dnf -y update kernel*
reboot

After restart and re-logging download and install the guest additions from iso image:

wget https://download.virtualbox.org/virtualbox/6.0.4/VBoxGuestAdditions_6.0.4.iso
mkdir ./GuestInstaller
sudo mount ./VBoxGuestAdditions*.iso ./GuestInstaller
export KERN_DIR=/usr/src/kernels/$(uname -r)
sudo ./GuestInstaller/VBoxLinuxAdditions.run
reboot

And, to have access to shared folders:

sudo usermod -aG vboxsf "$USER"
rm ./VBoxGuestAdditions_6.0.4.iso
rm ./GuestInstaller -r

Problems occur at sudo ./GuestInstaller/VBoxLinuxAdditions.run part. It Results in error modprobe vboxsf failed

Originally, I thought that VBoxAdditions 6.0.4 does not support kernel 5, but https://www.virtualbox.org/wiki/Changelog supposes that it has to support.

Also, sometimes it is recommended to export KERN_VER=$(uname -r) instead of export KERN_DIR=/usr/src/kernels/$(uname -r) : didn't work.

How to fix it and install?

Answer 1

Try installing VBoxGuestAdditions_6.0.6 This version resolve the build issue on kernel 5.0 or greater.

BUT! Since you are using Fedora. You can try installing Guest Additions via dnf package manager by typing dnf install virtualbox-guest-additions to install Guest Additions
