Let's change it back to mpv. (In general I prefer vlc, but mpv is more  
reliable for streaming.) and make sure that mpv is definitely installed$ sudo  
apt install mpvand try again.

If it still doesn't work, run $ sudo apt update
$ sudo apt upgrade 'apt update' will update the Trisquel repository and any  
PPAs you have installed to reflect available upgrades. 'apt upgrade' will  
upgrade any upgradable packages you have installed. I should have had you run  
'apt update' after adding the PPA but it slipped my mind.
