Ubuntu/Debian

We have an experimental GUI installer (x86_64) for Ubuntu 18.04 Desktop and newer and Debian Buster w GUI and newer. There is also an experimental GUI installer for ARM64 Ubuntu and Debian/Raspberry Pi OS 64. Binary CLI tools can be found in /usr/lib/chia-blockchain/resources/app.asar.unpacked/daemon/

Follow below install instructions for Ubuntu 20.04 LTS. If you are installing on Ubuntu 18.04 LTS you should use Python 3.7 instead: 

sudo apt-get install python3.7-venv python3.7-distutils python3.7-dev git -y

sudo apt-get update
sudo apt-get upgrade -y

# Checkout the source and install
git clone https://github.com/Chia-Network/chia-blockchain.git -b latest --recurse-submodules
cd chia-blockchain

chmod +x ./install.sh
sh install.sh

. ./activate

# The GUI requires you have Ubuntu Desktop or a similar windowing system installed.
# You can not install and run the GUI as root

chmod +x ./install-gui.sh
sh install-gui.sh

Troubleshooting
Sometimes stray daemons left over from previously running processes will cause strange bugs/errors when upgrading to a new version. Make sure all daemons and chia processes are killed before installing or upgrading.

This is normally done by executing chia stop -d all from the upgrade example above.
But it doesn't hurt to double check using ps -aux | grep chia to make sure there are no chia processes left running. You may have to manually kill the chia daemon if an install and chia start was performed without first running chia stop -d all

If all else fails, rebooting the machine and restarting the chia daemon/processes usually does the trick.
