Fix GH Action on ubuntu-latest

[andrewdavidmackenzie]

Development works fine loclly on macos and linux (Ubuntu).
GH Action passes on Macos, but after a lot of time spent trying to get GH Linux build passing I decided to give up and move on to other things.
I may come back to it, but probably someone more knowledgeable on Linux could fix this much faster than I can.
I will be checking it continues to build and pass tests on Linux locally in the meantime.

Example of failing linux build:
