Version 5.0.24 on Ubuntu16.04LTS

[jbg70]

Hi,
I just installed 5.0.24 64bit on fresh Ubuntu server 16.04LTS.
I used the repository virtualbox repository (debian xenial contrib).
Installation went fine no errors, I have to use virtualboxweb-service, but there is no virtualbox file in /etc/default/ and the service does not start.
Even creating a new file, the service does not start.

If I use ubuntu official repository, I get version 5.0.18; /etc/default/virtualbox file is OK and the vboxweb-serivice runs.

Installation bug or my issue?

Thanks for any helpful hint.
