@derlars, I'm the virtualbox maintainer, I asked to sync the kernel modules, because I'm pretty sure with signature verification enabled you can't just install the dkms package.
So I was hoping the official kernel virtualbox module (the one embedded in linux kernel) was signed with the same key.
I still think that removing --purge the virtualbox-dkms and installing the kernel vbox module should fix the issue.
