Install Chrome

wget -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' | sudo tee /etc/apt/sources.list.d/google-chrome.list

Using add-apt-repository using google’s source list result in error as it exports both i386 and amd64 but 18.04 doesn’t support i386 and complains.

sudo apt update
sudo apt install --no-install-recommends xorg openbox google-chrome-stable pulseaudio
sudo usermod -a -G audio $USER
