A (possible still broken) wget invocation that would get a token (we've managed to register an oauth app and had the network die on us once more when trying to get a token; what made it more annoying that it should have been is that that wget was old enough not to support storing bodies of errors, so there was lots of guesswork involved).
@robryk @js @timorl sorry about that network issue. The raspi4 in the 3D printed Lear terminal clone was doing the wifi-ethernet bridge to the A3000's ultra rare A2065 ethernet card, but the local wifi was so dodgy that I had to use my phone's hotspot instead ... So when I went fetch a drink it was too far...
