[Solved] 'RTR3Init failed with rc=-1912 (rc=-1912)' error

[Critical_Error]

Hi,

I initially installed Virtualbox 5.1.30-dfsg-1 from the snap store on my Ubuntu 17.10 machine. I had created a Windows 7 and REMnux virtual machine using this version of virtualbox.

Was in need of USB 2.0 and USB 3.0 support so went on to download the 'VirtualBox 5.2.4 Oracle VM VirtualBox Extension Pack' only to get an error stating the extension pack was incompatible with the current version of Virtualbox I had installed.

So I went on to uninstall 5.1.30-dfsg-1 and install the latest version 5.2.4 r119785. I then decide to install the extension pack before launching my WIndows 7 VM only to get the 'RTR3Init failed with rc=-1912 (rc=-1912)' error. I tried launching my REMnux VM only to get this same error as well.

What can I do to fix this?

Here is a more detailed info on the error:

Code: Select all

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.

I've been able to resolve the issue. The steps I took to do so include:

1.

Code: Select all

sudo apt-get autoremove

2.

Code: Select all

sudo /sbin/vboxconfig

Everything seems to be fine now.
