severity 509574 normalthanks Similar problem for me here: the lines
deb http://httpredir.debian.org/debian stable-proposed-updates main non-free contrib deb-src http://httpredir.debian.org/debian stable-proposed-updates main non-free contrib in /etc/apt/sources.list lead to W: Konflikt bei Distribution: http://cdn-fastly.deb.debian.org/debian stable-proposed-updates InRelease (stable-proposed-updates erwartet, aber stretch-proposed-updates bekommen) upon running "aptitude update". In different disguises, this problem exists for years.
