Last maintainer of virtualbox binary modules has resigned.
These packages are generated from virtualbox-guest-dkms and virtualbox-host-dkms each time a new linux or linux-lts package are released.
Is there a volunteer to take care of them and handle rebuilds ?
Although, I would prefer remove them and let users build vbox modules with the dkms package. That handle perfectly multiple kernel installation and simplify our job.
 virtualbox-guest-modules, virtualbox-guest-modules-lts, virtualbox-host-modules, virtualbox-host-modules-lts.
