Gnome's Boxes is pretty easy to use and of course uses qemu + KVM. This would be a type 1 hypervisor vs. Virtualbox's type 2. It is point and click like Virtualbox. You don't need to use Gnome's DE to use Boxes.
I have seen people post about your specific error for years when using the virtualbox website's repository instead of their own distro's repository (if it exists).
I'm trying to run VirtualBox in Linux Mint but I keep getting an error message about Kernel drivers.
