These instructions describe how to use a Joulescope with a Raspberry Pi 4 B with 8GB RAM.
Install Ubuntu with desktop and dependencies:
USe Raspberry Pi imager to install Ubuntu Server 20.04 LTS x64 on SD card.
Insert SD card into Raspberry Pi 4 and power on.
Login with username 'ubuntu' and password 'ubuntu'. Set new password.
sudo apt update
sudo apt upgrade
free -m
git clone https://github.com/wimpysworld/desktopify.git
cd desktopify
sudo ./desktopify -de ubuntu
sudo apt install python3-pip python3-venv
sudo reboot
Open terminal (CTRL-SHIFT-T) or ssh ubuntu@{ip_addr} and type:
wget https://raw.githubusercontent.com/jetperch/pyjoulescope/master/99-joulescope.rules
sudo cp 99-joulescope.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules
Connect your Joulescope
python3 -m venv ~/venv/joulescope
. ~/venv/joulescope/bin/activate
pip3 install -U joulescope

This setting can also be found by running software-properties-gtk.
sudo apt update && sudo apt upgrade
sudo apt build-dep qt5-default
sudo apt install libxcb-xinerama0-dev build-essential cmake llvm-dev llvm-runtime
I also did this before I learned about "sudo apt build-dep qt5-default":
