Just updated volumio to 2.873 on a raspberry pi 3 with 400 gb sd card and and allo digione. Tried updating spotify connect. But it returns the subject error. Any help appreciated. Local music directory seems to work fine.
Seems your Pi shut down while Volumio was still accessing the SD-Card.
You can putty to your pi and try to delete the content of /data/temp:
remove dirs: sudo rm -rf /data/temp/
