I am trying to install VirtualBox following this tutorial.
I have done every steps but when trying to run :

/usr/lib/virtualbox/vboxdrv.sh setup

I get following output :

vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.

/var/log/vbox-install.log contains :

make V=1 CONFIG_MODULE_SIG= -C /lib/modules/4.16.16-200.fc27.x86_64/build SUBDIRS=/tmp/vbox.0 SRCROOT=/tmp/vbox.0 -j8 modules
make[1]: warning: -jN forced in submake: disabling jobserver mode.
Makefile:978: *** "Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel". Stop.
make: *** [/tmp/vbox.0/Makefile.include.footer:101: vboxdrv] Error 2

So I have been trying to run dnf install elfutils-libelf-devel, but it is already installed :

Package elfutils-libelf-devel-0.170-10.fc27.x86_64 is already installed, skipping.
Dependencies resolved.
Nothing to do.
Complete!

Do any of you already ran into this issue or have an idea on how to fix it ?
Thanks guys !

edit :
I noticed it may be interesting to make sure elfutils-libelf-devel comes from the right repository, so output of dnf info elfutils-libelf-devel is :
