For a very long time now, I have not been able to update using OTA in Volumio. I have a MyVolumio Virtuoso subscription.
I had difficulties with a Raspberry Pi 3 but acknowledge that I was editing the config.txt file, so I thought no further about it.
Now I have an Asus Tinker Board S and perform no customisations. I am on v2.657 and I can Check Updates and it tells me that v2.671 is available. I let it update and after it has restarted I am still on v2.657.
Volumio simply never updates successfully OTA for me. I always have to re-burn the image to SD card, meaning I lose all my settings.
The only thing in common here is my MyVolumio subscription. Could there be something there stopping it from working properly?
