Could you please advice what should I do ? Otherwise system works perfectly. I know that is something with Linux, but I dont know exactly what to do. There is enough space on card.
Just see you’re still running Volumio2.
Spotify and Spotify connect for Volumio 2 are no longer working.
Please upgrade to Volumio V3 and install the Spotify plugin form the plugin list.
Just use a new SD-Card to flash. In that case you can always fall back. Hower something is wrong with your current SD as the Overlay is fully occupied as @gkkpch already mentioned.
Peppy_meter works like a charm on Volumio V3.
Just use this download. And the instructions as given under Download as Plugin
If you made custom templates for Peppy_meter make sure to back them up (/data/plugins/miscellanea/peppy_screensaver/peppymeter)
Same goes for the IR-Remote-Controller plugin. Backup your configuration (/data/plugins/system_hardware/ir_controller/configurations)
Well if you know what takes up this space, you might.
You can run a command like below, but this is beyond the support I will provide.
It will return the top 10 of big files
sudo du -aBm / 2>/dev/null | sort -nr | head -n 10
But be sure that you know what you’re doing, if you delete system files, it’s game over!!!
