The problem is that virtualbox-ose-modules-* does not depend on virtualbox-ose, which makes sure the user exists. And if you install both packages together, the user is not created yet, when the modules package expects it to be.
The problem can be reproduced as follows: $ sudo groupdel vboxusers $ sudo apt-get remove --purge virtualbox-ose virtualbox-ose-modules-2.6.22-14-generic $ sudo apt-get install virtualbox-ose virtualbox-ose-modules-2.6.22-14-generic [,,,] The following NEW packages will be installed: virtualbox-ose virtualbox-ose-modules-2.6.22-14-generic 0 upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
