I'm running Kubuntu 12.04 with the lts-raring hardware enablement stack. When I first installed the lts-raring hardware enablement stack I had problems with virtualbox but I resolved those (see "Background" below). However, a recent update caused new and more severe problems. Whenever I try to start a virtual machine at the moment the virtual machine boots into the GUI, my entire system (the host OS) crashes (it instantly reboots without warning).

In researching this I see the following bug report:

Bug #1127101 “Installing LTSEnablementStack in Ubuntu 12.04.2 breaks VirtualBox”

Temporary workaround : uninstall Virtualbox and install Virtualbox-4.2 from Oracle repositories. See here for instructions :

Is that the best solution or the recommended approach? Is anyone else seeing this issue?

Here's some system info:

$ uname -r

$ dpkg -s virtualbox
Package: virtualbox
Status: install ok installed
Maintainer: Ubuntu Developers <>
Architecture: amd64
Version: 4.1.12-dfsg-2ubuntu0.3


How I initially resolved the problem:

Comment #13 : Bug #1076603 : Bugs : “virtualbox-guest kernel module fails to build on 3.7.0 kernel”

wget -O /tmp/virtualbox.patch ';filename=vbox-wheezy.patch;att=1;bug=696011' cd /usr/src/virtualbox-4.1.12/ patch -p4 < /tmp/virtualbox.patch dkms autoinstall

I chatted with VirtualBox devs on IRC and they told me that Ubuntu does not regularly accept bug fixes from the VirtualBox devs. They recommended that I install the latest VirtualBox package from, which I did. That solved the problem.

The download link for Linux is:

It is actually a simpler install because you don't need to install guest additions separately. Uninstall the Ubuntu virtualbox packages using apt-get remove or purge.
