kernel driver not installed

Vbox 5.1.10 on Ubuntu 16.04 LTS

ed@ed-Gazelle-00:~$ uname -a
Linux ed-Gazelle-00 4.4.0-148-generic #174-Ubuntu SMP Tue May 7 12:20:14 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

When attempting to start a guest vm, I get two pop-up errors. The first:
(Well, I can't seem to attach the screen shot, so I'll transcribe the content):

VirtualBox - Error in suplibOsInit
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

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

and the second, again I cannot paste the image, but it did give the ability to copy the content:

Failed to open a session for the virtual machine vbdb112-01.

The virtual machine 'vbdb112-01' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}

Responding to the first:

Code: Select all

ed@ed-Gazelle-00:~$ sudo /sbin/vboxconfig
[sudo] password for ed: 
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: Look at /var/log/vbox-install.log to find out what went wrong.

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.

Possibly related, possibly not, when I try to download and install the newest v6 vbox for Ubuntu, the installer starts to show a progress bar, then quickly exits without any messages.

Never mind, I found the solution here: https://askubuntu.com/questions/1008150 ... ed-rc-1908

After executing

Code: Select all

sudo apt install --reinstall linux-headers-$(uname -r) virtualbox-dkms dkms

VBox started working again.

You didn't mention the output of:

• 
  VBoxManage -version

You might be running the Ubuntu fork, not the official VirtualBox.

sudo apt install --reinstall linux-headers-$(uname -r) virtualbox-dkms dkms

DKMS is not required for the official VirtualBox, not for anything > 5.0.x. From the 5.1.0 changelog:

• Linux installers: no longer rely on DKMS for module rebuilding

It seems that you may be running the fork after all...
