solve ubuntu 15.04 start virtalbox 5.0.8 NS_ERROR_FAILURE

把virtualbox升到最新之後，和4.X一樣，重開機後無法開啟。
但發現指令改了，

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing

'/sbin/vboxconfig'

as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

但重點來了
執行 sudo /sbin/vboxconfig 卻毫無反應。

總算還是在Google中找到資料

指令改成

sudo /usr/lib/virtualbox/vboxdrv.sh setup  

執行後就可以使用了。
