在Linux下安装VirtualBox出错解决方案

错误提示：

The character device /dev/vboxdrv does not exist.
     Please install the virtualbox-ose-dkms package and the appropriate
     headers, most likely linux-headers-generic.

     You will not be able to start VMs until this problem is fixed.

解决方法：

首先，根据出错提示，安装linux-headers-486.(使用 sudo aptitude 可以查看当前有那些包)。

然后重新配置VirtualBox:

sudo dpkg-reconfigure virtualbox-dkms

sudo dpkg-reconfigure virtualbox
