La clave que falta es la clave del repositorio de controladores unificado de Linux de Samsung. Siguiendo las instrucciones agregadas ael sitio webayer debería arreglar las cosas:

wget http://www.bchemnet.com/suldr/pool/debian/extra/su/suldr-keyring_1_all.deb
sudo dpkg -i suldr-keyring_1_all.deb

(¡suponiendo que confíes en el repositorio, por supuesto!).
