VirtualBox Installation gives message
sudo modprobe vboxdrv modprobe: FATAL: Module vboxdrv not found.
I have updated system with
sudo apt-get update
Ubuntu version: 14.04 LTS
I tried installing with GDebi Package Installer, the message is-
Selecting previously unselected package virtualbox-5.1. (Reading database ... 800789 files and directories currently installed.)

Another Try: I disabled secure boot from BIOS and followed
apt-get update apt-get install linux-headers-$(uname -r) dpkg-reconfigure virtualbox-dkms modprobe vboxdrv
Now modprobe vboxdrv working fine. So I installed VirtualBox with file- virtualbox-5.1_5.1.0-108711~Ubuntu~trusty_amd64.deb with GDebi Package Installer. Now when I start the VirtualBox and start a machine it shows following error-
**RTR3InitEx failed with rc=-1912 (rc=-1912)** The VirtualBox kernel modules do not match this version of VirtualBox. The installation of VirtualBox was apparently not successful. Executing '/sbin/vboxconfig' may correct this. Make sure that you do not mix the OSE version and the PUEL version of VirtualBox. where: supR3HardenedMainInitRuntime what: 4 VERR_VM_DRIVER_VERSION_MISMATCH (-1912) - The installed support driver doesn't match the version of the user.
