Não foi possível instalar o Virtual Box no Ubuntu 14.04

Question

Estou tentando instalar o Virtual Box no meu Ubuntu 14.04 Box. Eu baixei o arquivo de pacote do site oficial aqui

Eu tentei instalar este pacote, mas está causando erros. Abaixo está a informação reportada no terminal -

Answer 1

Você precisa desativar a inicialização segura nas configurações da BIOS.

Veja esta questão para mais detalhes.

O vboxdrv não está assinado e o Secure Boot não permite carregá-lo.

    

Answer 2

Você deve preferir a versão mantida pelo Ubuntu APT , a menos que você tenha necessidades especiais. Instale o VirtualBox usando o APT:

sudo apt-get install virtualbox
