Hi Mike
Shoo, what a learning curve I have gone through. All I suspect idiosyncrasies of Raspian / Linux (of which I know very little I do admit) rather than a short coming of Fruitbox.
I have eventually managed to load Fruitbox 1.10 onto a new sd card so as to keep V1.6 in case of.... well, who knows if I get this to work or not.
I have also used a new Memory stick/flash drive to preserve my old working unit and loaded my MP3's to that in subdirectory Music, sorry, that should be "music" Case sensitive again, almost caught me again.
Now for all the little points that messed me around as a record to help those who face the same problem. I can understand the frustration of that one chap who posted a short while back who said he is going back to XYZ because he couldn't get Fruitbox to work, so if he is still checking in, he should consider the following points that will trip you up as a clue to his problem.
1 - Changing Flash drive. - Assume nothing!
My first working drive working with Fruitbox 1.6 was mounted as sda as that is how the system identified it.
Now exactly the same Raspberry 3 identifies the new Sony Flashdrive as sda1 even though it is plugged into the same usb port. THIS is what was causing the Pi to boot up in Emergency mode as posted previously and hanging up. I could get past this by swapping to the first USB stick to get it to finish booting up though then returned the new USB and changed the
2 - Case Sensitive - "walljuke" does not = "WallJuke" ; "Music" does not = "music"
After getting past the booting issue, I got caught out with the problem that while Fruitbox was loading, the Fruitbox logo comes up and proudly displays 1.10, it would bomb saying that it was not being able to find the config file. "Unable to find skins/walljuke/fruitbox.cfg". The case sensitive problem again that I got caught out with the first time. I was typing "sudo skins/walljuke/fruitbox.cfg" and not the required "sudo skins/WallJuke/fruitbox.cfg"
I hope this all helps someone else. I am now doing a full back up of the sd card before I set up auto-loading.
Now a new problem that I know you cannot help with. My son is turning 21 in 6 weeks and he is so impressed with this having had it running in bare back fashion in our pub that he now badly wants this Juke Box to be built in the full size wurlitzer style cabinet we have seen online and running for his party.
