Не может запустить virtualbox на Ubuntu 16.04.2 LTS

Я уже установил и использовал virtualbox правильно. Однако, так как вчера я получаю эту ошибку при запуске virtualbox:

root@batzi-xubuntu:/home/batzinger# virtualbox
WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-dkms package and the appropriate
headers, most likely linux-headers-generic.

You will not be able to start VMs until this problem is fixed.
Qt WARNING: Qt: Session management error: Authentication Rejected, reason : 
None of the authentication protocols specified are supported and host-based authentication failed

Я также следовал ответу этого вопроса, но ничто не изменилось. после выполнения sudo склонный - добираются - переустанавливают установку virtualbox-dkms, я получаю следующий вывод:

Ну, возможно, у кого-то есть anonther идея?
