How do I set up Ros2 for Raspberry Pi 4 when link does not work anymore?

Under set up compute boards in create3 docs:
If you click on
Installing ROS 2 on Ubuntu Linux1 - official Open Robotics documentation
you will get the following

Not Found
The requested URL /en/galactic/Installation/Ubuntu-Install-Binary.html was not found on this server.

How do I set up galactic Ros2 when this link does not work?

That's not our documentation, but it's possible to get Ubuntu 20.04 on an SD card using the Raspberry Pi imager at https://www.raspberrypi.com/software/ , and then install ROS 2 by following the step-by-step instructions at https://iroboteducation.github.io/create3_docs/setup/pi4/#step-by-step .

Thank you for your response.
Yes I think I can get Ubuntu on the Raspberry Pi. However, how do I install Ros2 with no instructions?

[shamlian]

Oh, I see. You can follow the instructions on our page verbatim:
https://iroboteducation.github.io/create3_docs/setup/pi4/#step-by-step .

I'll have to see what happened to OR's docs.

[shamlian]

Looks like OR's Ubuntu install docs are now found at https://docs.ros.org/en/galactic/Installation/Ubuntu-Install-Debians.html or perhaps https://docs.ros.org/en/galactic/Installation/Alternatives/Ubuntu-Install-Binary.html; I will update the iRobot docs site. Thanks. You should be good to go if you just follow the step-by-step on the page that you originally navigated over there from.
