Error when trying to launch virtualbox machine in mac os x

[Paul5]

I get this when trying to load a ubuntu machine on virtualbox why

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

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {5047460a-265d-4538-b23e-ddba5fb84976}

Also i get this

Kernel driver not installed (rc=-1908)

Make sure the kernel module has been loaded successfully.

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

I would like some help to fix this issue.

The error says that the kernel extensions needed by VirtualBox aren't installed. There is a thread on Installation fails on 10.13.x, 10.14.x (rc=-1908). I would start by reading that thread and following the guidance there.

I am trying that but also the app fails to install is there a way to fix the issue.

[andyp73]

The normal process is run the installer (which will fail), allow Oracle as a vendor in the security settings, re-run the VirtualBox installer (which should succeed).

If it doesn't then there may be a permissions issue elsewhere and so can you post the output of running the single command:

ls -laed@ \
  / \
  /Applications \
  /Applications/VirtualBox.app \
  /Applications/VirtualBox.app/Contents/MacOS/VirtualBox \
  /Applications/VirtualBox.app/Contents/MacOS/VirtualBoxVM \
  /Applications/VirtualBox.app/Contents/MacOS/VBoxRT.dylib \
  /Library/Application\ Support/VirtualBox \
  /private \
  /private/etc \
  /private/etc/sudoers \
  /private/tmp
