So I upgraded my system but since after that I cannot use virtualbox I am getting the following error -
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 '/etc/init.d/vboxdrv setup' 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.
After this I followed on terminal and ran this command after which I got this result
please help as I am new to ubuntu and not very open with command system please let me know whats the problem. thanks in advance .....I need to run my windows 7 professional over virtual box
