Eu instalei o Kali no VirtualBox e agora estou tentando instalar o Guest Additions para obter visualização em tela cheia.
Eu atualizei e instalei meus pacotes e instalei o dkms. Quando tento instalar o linux-headers, recebo o seguinte:
# apt-get install linux-headers-$(uname -r)
Reading package lists... Done

Reading state information... Done
linux-headers-4.14.0-kali1-amd64 is already the newest version (4.14.2-1kali1).
0 upgraded, 0 newly installed, 0 to remove and 86 not upgraded.
Os cabeçalhos instalados são os seguintes:
# dpkg --get-selections | grep linux-headers
linux-headers-4.14.0-kali1-amd64 install
linux-headers-4.14.0-kali1-common install
linux-headers-amd64 install
Quando tento executar o CD de adições de comentários, recebo o seguinte:

Parece-me que os cabeçalhos de linux corretos para o kernal estão instalados. Por que o VBox não consegue encontrá-los?
Tentei atualizar para o VBox 5.2.2, mas após remover a versão existente e instalar o 5.2.2, não consegui iniciar o Kali-Linux - captura de tela anexada
