Unable to build Virtualbox 6.0 on Fedora 29 -> fixed after (not in) 6.0.4 and 5.2.26 and in test builds

After installing VirtualBox 6.0 on Fedora 29 and creating a rudimentary VM, I get the following message:

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing


as root.

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

sudo /sbin/vboxconfig Stopping VirtualBox services. Starting VirtualBox services. Building VirtualBox kernel modules. failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

There were problems setting up VirtualBox. To re-start the set-up process, run


as root.

dmesg has ABSOLUTELY NO messages about this.

Kernel Version: 4.19.13-300.fc29.x86_64

It's usually better and faster, if issues get first addressed in the VirtualBox forums, a lot more eyes there. More than 95% of the issues are resolved over there, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is most probably not a bug and someone from the developers has to deal with it and close it as "Invalid".

It looks like either you didn't download the appropriate package, or you downloaded the fork from the Fedora repository, or you're missing some building tools from your installation.

So, if you can, please open a new thread in the VirtualBox on Linux Hosts section of the forums. Please be sure to mention that you came from the bug tracker and include the ticket number.

You are generally right and after some investigations I found out that the problem was secure boot. But the message you display is not really helpful. So isn't it possible to give at least a hint that secure boot could be the problem?

Replying to pueffl:

That's not a bad idea actually, not bad at all!

I'm not personally very familiar with Linux and its intricacies, could you see if it's easy to detect Secure Boot, and potentially apply a fix/patch to the installation script so that it gives better feedback to the user?

It is actually not quite trivial to detect when module signing is needed, not least because different distributions have done slightly different things. I am thinking of extending the message with something like: "If your system has EFI Secure Boot enabled you may also 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." Does that sound reasonable?

Since you did not answer I did what I suggested (r77196). The change will be in the test builds in about an hour, though I doubt anyone will install one just to try this.

Resolution: fixed
Status: newclosed

Closing this, though it is possible that we will be working on it further in future. Ubuntu has its own solution for signing kernel modules which we might make use of. Debian looks like it will adopt it too. If other distributions also provide solutions we will certainly look at them. I am not aware of Fedora doing anything though at the moment.
