Thanks for reporting, please install the package software-properties-kde.
@Carlo installing it solved the problem. Thank you. Are you going to add that package as a dependency?
This must be fixed in packaging. Reported here: https://bugs.launchpad.net/ubuntu/+source/muon/+bug/1612392 I will consider adding a message in Muon when software-properties-kde is not found.
