On Ubuntu open the terminal and install:
sudo apt install -y rpi-imager
Please note that rpi-imager version that comes with Ubuntu package manager might be quite old. Please consider downloading the laster version from https://www.raspberrypi.com/software/.
After downloading provide execution permissions, and run the application as superuser:
chmod +x imager_2.0.7_amd64.AppImage
sudo ./imager_2.0.7_amd64.AppImage
