Building Chrome from source in Ubuntu 18 & 20

chrome_build_ubuntu.sh

# Based on:
# https://chromium.googlesource.com/chromium/src/+/master/docs/linux/build_instructions.md#System-requirements

# Easiest path is to use Ubuntu 18.04 *Desktop*
# It will bring along a lot of the critical system GUI & font dependencies

# Only needed for 18 minimal, not 18 full or 20:
# echo "shmfs /dev/shm tmpfs defaults,size=58G 0 0" | sudo tee -a /etc/fstab

# Assumes we're running in a container/VM, otherwise don't run as root

# Is 2.7 required?
# Can I use repo pip?
sudo apt-get install -y git python2.7-minimal python curl
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py
