On one of my two RPIs running Volumio (2.344) I’m not able to install the Spotify plugin. Something went wrong the first time I tried installing it and now if I want to install it again I get the error “Error: Plugin spop already exists”. What can I do to fix this?
You can manually delete the plugin directory from disk (/data/plugins…) or use the factory reset option.
The problem turned out to be a broken SD card, which had gone into read only mode. A fresh installation on a new SD card solved all my issues
