Sense Hat to work on Pi 3 B running Ubuntu Mate 18.04.3 LTS

Hi there,

I need to roll out a large number of Raspberry Pi 3Bs running Ubuntu Mate.

We have gone for Ubuntu Mate as Raspbian had major issues connecting to WPA2 Enterprise networks. Ubuntu Mate is working fine for this, but now I have issues with the Sense Hat.

Mate version is 18.04.3 LTS. Python version is 3.6.9.

I have installed Mate, run a sudo apt update and a sudo apt upgrade. Everything else seems to be working fine so far, but when I try to install the sense-hat package via the instructions here: https://projects.raspberrypi.org/en/projects/getting-started-with-the-sense-hat/2 I get:

[email protected]:~$ sudo apt-get install sense-hat
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package sense-hat

Within Python I try to run from sense_hat import SenseHat and I get ModuleNotFoundError: No module named 'sense_hat'

The sense hat does light up on powering on, but then once Mate fully loads the lights go off. It is a known working sense hat.

Does anyone have any suggestions? I'm guessing I need to install the sense hat package and Mate can't see that for some reason?

Thanks
Andrew
