Installation of Simple Equalizer Plugin fails

@Balbuze, I am very interested in installing your plugin Volumio Simple Equalizer 0.4.1. I’m installing it through the web GUI under “Plugins>Audio interface”. But, it always fails to install:

I use a Raspberry Pi 3 with Hifiberry Amp+. Any ideas? The error message sure doesn’t give any hints.

Hi,
What is your device and version of volumio? Have you installed other plugins? Have you changed the default sudo password?

I just installed it on afresh install (rpi2 + volumio “myvolumio 1.002”), and it just works as expected with iqaudio dac.

@Balbuze: Thanks for your tip on restoring the default password. That did it! Must thank you for this wonderful capability I previously had to use console commands for.

Maybe the error message could be more elaborate, I had no idea changing the default password would deny me installing plugins.
