Xubuntu 16.04 & Virtualbox: "Failed to start LSB"

[^rooker]

Fresh install of Xubuntu 16.04.3 (64bit).
When installing the "virtualbox" package, I got the following error:

Job for virtualbox.service failed because the control process exited with error code. See "systemctl status virtualbox.service" and "journalctl -xe" for details.
invoke-rc.d: initscript virtualbox, action "restart" failed.

Trying to install the package again, just says everything's fine.
Hm...
