VirtualBox Guest Additions: modprobe vboxsf failed
You can try loading the kernel module yourself to see what the error message is.
One likely cause is that you are using an EFI system with secure boot enabled. In that case you either have to disable it or sign the kernel module and add the key to the EFI table using mokutil.
I believe this is a VirtualBox problem. The setup log shows...
