ii dkms 2.3-3ubuntu9.1 all Dynamic Kernel Module Support Framework
ii virtualbox-dkms 5.2.10-dfsg-6 all x86 virtualization solution - kernel mod
I have verified that with the old dkms, kernel upgrades lead to an unsigned vboxdrv module; and with the new dkms, kernel upgrades do have signed modules that load correctly with SecureBoot enabled.
Verification-done on bionic:
