I ran into a problem with the new A04 image file after booting it.

They have been ignored, or old ones used instead. Not being too bright I tried using the Internet techniques to no avail. I did notice that the github URL does not identify the specific software package for updating. Can someone provide the proper commands to correct this situation, not just for me but for others who may run into the same situation? ---
