Unable to update crouton after installing VirtualBox

Leave a comment

When trying to update crouton I kept getting the following error message:

Preparing to unpack .../linux-image-3.8.11_20150314_amd64.deb ...
Ok, aborting, since modules for this image already exist.
dpkg: error processing archive /var/cache/apt/archives/linux-image-3.8.11_20150314_amd64.deb (--unpack):

After some digging I found this thread which explains how to fix it. The source of the problem was the fact that I had installed a modified kernel to allow VirtualBox to work properly. The way to update crouton is to remove the repository for that kernel

rm /etc/apt/sources.list.d/crouton-packages.list

After removing that repository the update completed successfully.

Fix No USB devices connected in Virtualbox

Leave a comment

Recently on my Linux Mint 13.2 system I was playing with Virtualbox. I wanted to pass through a USB device to a virtualbox VM but despite installing the appropriate extension pack, I was greeted with this lovely message in the USB menu:

No USB devices connected

I discovered here that you need to be a member of the vboxusers group. One quick command solved this:

sudo usermod -a -G vboxusers <username>

Once I did that I logged out and logged back in. Voila! USB passthrough worked.

Install Virtualbox on a Chromebook

18 Comments

I am really enjoying my Chromebook Pixel 2015. Recently I needed to spin up a few VMs on this box. I tried to install virtualbox but it turns out that the kernel for the chromebook does not include virtualbox headers. Fortunately it’s fairly easy to add them, thanks to divx118’s scripts.

First, enable the necessary chromebook kernel flags. Run these commands in a crosh shell (not in a chroot)

cd ~/Downloads
wget https://raw.githubusercontent.com/divx118/crouton-packages/master/change-kernel-flags
sudo sh ~/Downloads/change-kernel-flags

Note: You will need to repeat the above steps after each chromeos update.

Next, open up a chroot shell and do the following:

cd ~
wget https://raw.githubusercontent.com/divx118/crouton-packages/master/setup-headers.sh
sudo sh setup-headers.sh

Lastly, reboot the chromebook. Once you’re back up, enter your chrooted environment and install Virtualbox from their Oracle’s download page. Don’t use the virtualbox repositories – they don’t work.

Install the downloaded deb file with dpkg

dpkg -i virtualbox-5.0_5.0.10-104061~Ubuntu~trusty_amd64.deb

You might get this error:

dpkg: dependency problems prevent configuration of virtualbox-5.0:
 virtualbox-5.0 depends on libqt4-opengl (>= 4:4.7.2); however:
  Package libqt4-opengl is not installed.

The fix to that error is to run the following command to install missing dependencies:

apt-get -f install

If you get weird errors about VT-X not being enabled in the BIOS, try running the script and rebooting again.

Success!
