Distributor ID: Ubuntu
Description:    Ubuntu 23.10
Release:    23.10
Codename:   mantic

Following along with tutorial https://projects.raspberrypi.org/en/projects/getting-started-with-the-sense-hat

The code I was using is not very fancy; just:

hello.py

from sense_hat import SenseHat

# print hello world
print("Hello, world!")
sense = SenseHat()

sense.show_message("Let's have piklets for breakfast!")

I'm aware that I should be able to switch to https://www.raspbian.org/ but I would like to find others to help me put time/effort into getting this to work more broadly, hence logging this issue.

Ask on the Pi forum. This isn't really a bug. It's a setup with Ubuntu as you'll need to install it, or activate the overlay, and use Python however Ubuntu wants you to use it. There would normally be no need to run eleveted either. At least not in RPiOS.

I suggest you grab another sd card, us RPiOS and see how it works there, then work backwards once you have the feel.

Hi @bsimmo - Amazed at the quick reply. Yes, if you want to close this ticket as it is not a bug that is fine. I have this on my backlog of hobby tasks to do.

Hi subject matter experts, if you want to pair up on this one please get in touch.

Closing.
