Hi, >Some months ago I installed the backported nvidia drivers. >Recently there was an update to stable that left me here, >where I have a backports version that is now lower than the stable >version > % dpkg --compare-versions 390.87-8~bpo9+1 lt 390.87-8~deb9u1 imho this is a mistake by the person who updated stable and was missed by the stable release managers. The stable update suffix should be +deb9u1, not ~deb9u1. -nik
