Hi toracat,
Thank you very much for your reply.
It’s sorted now.
For future reference what I did was, I removed the kernel 6.8.3 headers with the command:
$ sudo dnf --enablerepo=elrepo-kernel remove kernel-ml-headers
Then installed the kernel devel module with the command:
$ sudo dnf --enablerepo=elrepo-kernel install kernel-ml-devel
And then I ran the command to reconfigure VBox:
$ sudo /sbin/vboxconfig
It’s sorted.
Thank you very much,
Cheers
