LMDE og opdateret

Hej

Jeg har installeret LMDE på min laptop, men jeg har fået problemer med og opdateret.
Her er min sources.list

deb http://linux-mint.froonix.org/ debian main upstream import
deb http://debian.linuxmint.com/latest testing main contrib non-free
deb http://security.debian.org/ testing/updates main contrib non-free
# deb http://www.debian-multimedia.org testing main non-free
deb http://debian.linuxmint.com/latest/multmedia testing main nonfree

#Spotify
deb http://repository.spotify.com stable non-free

Også når jeg køre sudo apt-get update får jeg dette svar
