A clear and concise description of what the bug is and how it can be reproduced.

git clone on an arm64 machine (I was working on an AWS Graviton-2 based VM). . ./install

Environment:

• OS: Ubuntu 20.04
• Python version: 3.8
• PIP version: 21.1.1
• Chia version: 1.1.5

This was due to a missing package dependency. Perhaps this needs to be added to the install script?

sudo apt install python3-dev

I recently had a similar problem with additional package dependency problems, and I solved it. See here: https://github.com/martomi/chiadog/issues/148

Thanks, I have a branch ready for this that adds the following line to the install.sh file

# Install dev tools
sudo apt-get update
sudo apt-get install libpython3-dev build-essential -y
