Upgraded ubuntu from 14.04 to 16.04 lts -Virtual box problem

Question

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

Answer 1

The answer to your problem lies here under "Note 4":

Running DKMS in the guest OS will keep Guest Additions installed after a guest kernel update.

I believe your host machine suffers of the same problem!

I'll divide my instructions in two parts: part one for installing virtualbox and part two for installing guest additions.

PART ONE: Installing virtualbox from debian package

I just did this in a fresh Ubuntu Mate installation (much better than the basic distribution!) because Ubuntu Software Center didn't give me the latest version which is 5.1.2.

Next steps in host's terminal:

I followed this link

1. sudo apt-get update

2. sudo apt-get install dkms

3. Download virtualbox-5.1_5.1.2-108956~Ubuntu~xenial_amd64.deb from link (amd64 in filename is NOT for AMD only)

4. sudo dpkg -i Downloads/virtualbox-5.1_5.1.2-108956~Ubuntu~xenial_amd64.deb

Errors appear so, rebuild

5. sudo apt-get -f install

Redundant:

sudo apt-get install build-essential linux-headers-$(uname -r)

sudo rcvboxdrv setup

6. run virtualbox

if message about errors, reconfigure with sudo /sbin/vboxconfig

Finally, add a Virtualbox menu item with this superb tool that only Ubuntu Mate offers(!)-the all mighty alacarte command of previous decade and broken in newer versions of Ubuntu!: System->Preferences->Look and Feel->Main Menu

PART TWO: Installing guest additions

A proper installation is described here although, the writer forget to mention that everything is being executed in the guest!!!

Even so, problems existed in my case so I mixed previous link with this and here the final steps:

7. Create a Ubuntu guest server graphically or use an existing one with a name, e.g. My Ubuntu Server

8. copy *.iso to your guest folder My Ubuntu Server

cp /usr/share/virtualbox/VBoxGuestAdditions.iso ~/'VirtualBox VMs'/'My Ubuntu Server'

9. on Virtual Box Manager (main window) select the just copied file

In the picture it's obvious that I already did it!

Next steps in the guest's terminal:

10. sudo apt-get update

11. you should have dkms:

dpkg-query -s dkms | grep -i status Status: install ok installed

otherwise

sudo apt-get install dkms

12. now it's time to rebuild guest additions:

sudo mount /dev/cdrom /mnt

cd /mnt

sudo ./VBoxLinuxAdditions.run

reboot

13. when logged again run sudo mount | grep vbox and in my case the shared folder is in /media/sf_shared
