Looks like they have changed/updated their public key.. Interesting as I just installed upmpdcli in my test rig on my test rig just last week and it worked. Perhaps the script is not updated on the RPi platform.

Hopefully I will find some time this weekend to look into this. Will be taking a christmas break from Dec 24th onwards until next year. Not much of a break. With any luck will clear up some loose ends then.
