Linux – VirtualBox Guest Additions 6.0.10: modprobe vboxguest failed

I'm having "issue" while installing VirtualBox Guest Additions 6.0.10 on CentOS 8.

[VBox_GAs_6.0.10]# ./VBoxLinuxAdditions.run will end up with following error

[VBox_GAs_6.0.10]# cat /var/log/vboxadd-setup.log
modprobe vboxguest failed

I've already installed following [see bellow] and re-run "./VBoxLinuxAdditions.run" but still having issue.

[VBox_GAs_6.0.10]# yum install dkms binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers 

[VBox_GAs_6.0.10]# yum install kernel-devel

Some more information

[VBox_GAs_6.0.10]# uname -r
4.18.0-80.el8.x86_64

[VBox_GAs_6.0.10]# cat /proc/version
Linux version 4.18.0-80.el8.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 8.2.1 20180905 (Red Hat 8.2.1-3) (GCC)) #1 SMP Tue Jun 4 09:19:46 UTC 2019

Even I have installed kernel-headers by just enabling debug mode in bash for "VBoxLinuxAdditions.run" it complains about following VirtualBox Guest Additions: Kernel headers not found for target kernel 4.18.0-80.el8.x86_64. Please install them and execute.

And of course Package kernel-headers-4.18.0-80.11.2.el8_0.x86_64 is already installed.
