VirtualBox Fails To Install ISO's on Start

[shamrock1961]

I'm currently running the latest Ubuntu package 16.04 64. Prior to that I was running 15.10. I upgrade from 15.10 to 16.04. Ever since then VB does not want to install on "Start" any of the iso's I want to use in a virtual environment. I get this error:

Failed to load R0 module /usr/lib/virtualbox/VMMR0.r0: World writable: '/usr' (VERR_SUPLIB_WORLD_WRITABLE).
Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).


Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}


I have yet to see anything about on the Ubuntu forums. I did install these versions:virtualbox-5.0_5.0.16-105871, virtualbox-5.0_5.0.18-106667 and virtualbox-5.0_5.0.20-106931 all DEB files for AMD64. The 5.0_5.16 version worked fine with Ubuntu 15.10. Then came the upgrade to 16.04 and problems started. I cannot use VB at all as it will not install the ISO's I previously used prior to the Ubuntu 16.04 upgrade. I have done complete removals and reinstallations with no results.

Any clues as to what is happening here?

At some point the permissions for /usr/lib was changed to be owned by someone else and you need to fix that before you can proceed. How could this happen? Some programs ( not VBox ) do this and maybe the upgrade, but not sure about that one.

run the following in the hosts terminal to see what the actual permissions are:

Code: Select all

ls -Al /usr/lib
