Install Kali Linux on Chrome OS Crostini

Most of these instructions are modified from :

• Arch Install (here)
• Chromium OS Docs (here)

Install Kali Container

Open Crosh (Ctrl+Alt+T), and then run the following command to install the Kali container through LXD. You might get an error here, ignore it:

vmc container termina kali https://us.images.linuxcontainers.org kali

Now enter the kali container:

vsh termina
lxc exec kali -- bash

Install sudo:

apt install sudo

Find the non-root user that was created (your username):

grep 1000:1000 /etc/passwd|cut -d':' -f1

Give this user a password and sudo permissions:

passwd <username>
usermod -aG sudo <username>

Switch to the non-root user:

su - <username>

Make sure you have network connection. You should see a non-empty result:

ip -4 a show dev eth0

If you see an empty result, I'm honestly not sure what to do. Consult other articles!

Integration with Chrome OS

I installed a couple packages that were recommended in other articles, but I am not sure if it was necessary:

sudo apt install -y gnupg2 psmisc

Add Google's cros-package repo. Start by switching into root user so that sudo echo works:

sudo -i
sudo apt install ca-certificates
sudo echo "deb https://storage.googleapis.com/cros-packages stretch main" > /etc/apt/sources.list.d/cros.list
if [ -f /dev/.cros_milestone ]; then sudo sed -i "s?packages?packages/$(cat /dev/.cros_milestone)?" /etc/apt/sources.list.d/cros.list; fi
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1397BC53640DB551
exit # to get back to non-root user

Then update:

sudo apt-get update

Finally, install cros-guest-tools to enable integration with Chrome OS:

sudo apt install cros-guest-tools

Enable graphical integration:

systemctl --user enable --now sommelier@0 sommelier-x@0 sommelier@1 sommelier-x@1

Allow apps to run in the background:

loginctl enable-linger <username>

Before I could get GUI apps to run (e.g. gnome-terminal) I had to exit the container and re-enter:

exit # until you are back to Termina
lxc exec kali -- bash
su - <username>

I installed gnome-terminal to test a gui program, but hopefully others will work as well!
