1. installation of Raspberry Pi imager from official website
Select the operating system as Ubuntu Server 20.04. However, there is no ubuntu desktop in that case. So you have to install the ubuntu-desktop manually. Configure your own password and user name.

Upload the operating system to the SD card.

If you work or study at China, you have to modify the download source to make the downloading process stable.
cd /etc/apt
cp sources.list ./sources.list.bak
sudo sed -i 's/ports.ubuntu.com/mirrors.ustc.edu.cn/g' sources.list
And then:
sudo apt update
sudo apt upgrade
4. install the ubuntu-desktop
The shell command is :
sudo apt install ubuntu-desktop
5. ROS noetic installation
wget http://fishros.com/install -O fishros && bash fishros
Select the option that matches your own device.

If you want to install vscode, turn to [5] and re-select installation option.
