Next, I was going to start learning ROS, but it was particularly difficult to install it on the Raspberry Pi operating system. I tried to install ROS on the 32-bit buster operating system for a long time but failed. It was even more difficult to install it on the 64-bit bullseye version. Moreover, I didn't want to go back to the 32-bit system after knowing that the 64-bit system was a huge improvement over the 32-bit system.

Finally, I decided to use Ubuntu and switch back when the 64-bit version of the Raspberry Pi can easily install ROS.

Method 1: Install MATE desktop version directly

There is no 20.04 desktop version available for Raspberry Pi on the Ubuntu official website. It can be found on the website , as shown below.

The version is 20.04.1, and the server version has been updated to 20.04.4. Obviously, the Raspberry Pi desktop version has not been updated any more. It can be upgraded to the latest version through the internal upgrade of the operating system.

The installation of the Ubuntu desktop version has been introduced before .

Method 2: Install from the server version

The desktop version is the server version with an additional desktop. The server version can be downloaded from Ubuntu's official website .

Use the Raspberry Pi image burner to burn. After running, you will be asked to enter the username and password. The username and password are both ubuntu. You will be forced to change the password. Enter the following command to install the desktop

sudo apt install ubuntu-desktop

It takes about a few hours to install the desktop, and then it automatically enters the desktop when restarting, as shown below.

This is the default GNOME3 desktop, which looks good, but is very laggy. You can install MATE desktop to improve it. Enter in the terminal:

sudo apt install ubuntu-mate-desktop

After restarting, select MATE desktop in the upper right corner of the password input box, as shown below.

The interface is as follows.

All settings and files are preserved between different desktops. MATE desktop has fewer animations and is quick to respond. However, GNOME3 desktop still has many more features, such as remote desktop.

After a lot of trouble, I found that whether you directly install the MATE desktop version of Ubuntu or install MATE desktop from the server version, the final result is the same. In addition, there are many more things when you directly install the desktop version, such as make and gcc, and the Raspberry Pi-specific welcome interface.

question

What are the differences between Ubuntu and Raspberry Pi systems? Can I run the code previously written on the Raspberry Pi system on Ubuntu?
