Error when installing Ampswitch plugin

[ecoplan]

Hello, I try to install the Ampswitch plugin, but each time I receive this error. I tried to do it via shell with the github repo and same problem:

Downloading plugin at volumio.github.io/volumio-plugin … switch.zip
END DOWNLOAD: volumio.github.io/volumio-plugin … switch.zip
Creating folder on disk
Unpacking plugin
Checking for duplicate plugin
Copying Plugin into location
Installing dependencies
The following error occurred when installing the plugin: Error

Any idea?

Thanks

Bump. One last try before reinstalling Volumio

FYI, I get this error when I try to install the majority of plugins.
