    Welcome to AskUbuntu. If you write out the error message it will be easier for you to find a resolution. The system will even give suggestions where the same errors has been resolved by others. You loose this potential by using pictures rather than text. Also the images takes up a lot of unnecessary space on the server. Try to user images when text won't suffice. In this case the specific text error is clear. – L. D. James Oct 15 '16 at 12:02
  • Most dialogue windows in Linux let you select, copy and paste their text content by the way. – David Foerster Oct 15 '16 at 22:05
  • i'll keep the suggestions in mind from next time onwards :) – Deepak Kumar Oct 16 '16 at 18:42

    These instructions work for Ubuntu 17.10: sudo apt-get autoremove sudo /sbin/vboxconfig from this post on VirtualBox Forums – Walker Rowe Apr 16 '18 at 9:38

The image in the picture is giving you this error message: rtr3initex failed with rc=-1912 (rc=-1912) Ubuntu

It's telling you you have a mismatched install. Your kernel modules do not match your installed version. The kernel modules are packaged in virtualbox-dkms in the repository.

You have most likely installed it from the repository. But failed to install all the modules, or you installed it, performed and upgrade and the modules didn't get completely upgraded during one of your system's updates. You can fix this by uninstalling it and reinstalling it, which will install the necessary modules. You do this with:

$ sudo apt remove --purge virtualbox
$ sudo apt install virtualbox
$ sudo apt install virtualbox-dkms

Completely removing virtualbox and it's dependencies will not affect your VM's. Just the applicaton itself.

Alternatively you can download the latest version of Virtualbox from http://Virtualbox.org. The download page for linux is: https://www.virtualbox.org/wiki/Linux_Downloads.

You can append this to your /etc/apt/sources.list file to add the official developers repository:

deb http://download.virtualbox.org/virtualbox/debian xenial contrib

You can download and add the security key with:

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

Then grade what you currently have with:

$ sudo apt update
$ sudo apt upgrade

If you purged the previous version then reinstall it with this after the upgrade command above:

$ sudo apt install virtualbox

If you download and install from virtualbox.org the kernel modules for the developers version will automatically be compiled and installed.

    Hello. I had VirtualBox 5.0.4 which freezes my system (I have Kernel 4.13.xx). Then I purged as you wrote above and installed using Virtual Box site. Yet I still get this message. What should I do? – Royi Mar 16 '18 at 7:09

    @Royi I take it that you are saying the error is the exact message. Run these commands: (1) sudo apt remove --purge virtualbox-dkms ; (2) virtualbox-dkms . You may have to run this afterward: /sbin/rcvboxdrv setup – L. D. James Mar 16 '18 at 12:48
  • I ran #1, but now #2 says doria@doria:/home/doria$ virtualbox-dkms virtualbox-dkms: command not found – David Doria Jan 17 '19 at 19:40
  • @L.D.James You don't need to run virtualbox-dkms (you removed it, no?). Anyway it works. – Marco Sulla Mar 10 '19 at 0:54


sudo apt-get autoremove
sudo /sbin/vboxconfig

    Welcome to Ask Ubuntu! Could you edit your answer to explain how this should help? – Melebius Sep 18 '19 at 9:50
  • This helped actually in my case. Thank you :) – Vadim May 2 '20 at 14:45
  • Worked for me! Ubuntu 18.04 host running Windows10 Guest. – Joel Aug 4 '20 at 14:53
