Debian Apt Update erlaubt keine DVDs

Ich fange wirklich an, mir die Haare auszureißen. Ich habe ein Debian-9-System ohne Internetzugang und versuche, ein passendes Update durchzuführen. Ich erhalte jedoch immer die gleiche Fehlermeldung (siehe unten). Ich habe mehrere Optionen ausprobiert, um unsichere Repositorys zuzulassen, aber nichts scheint zu funktionieren. Ich freue mich über jede Hilfe.

Hier ist meine apt-config, vielleicht kann sie etwas Licht in dieses bringen:

Update 2

Mir wurde gerade klar, dass ich mit i386 einen Multiarch eingerichtet hatte. Ich entfernte es jetzt mit dpkg --remove-architecture i386. Es wurden keine i386-Pakete installiert. Ich entfernte dann die DVD sources.listund fügte sie erneut hinzu, wobei apt-cdrom. Ergebnis gleich bleibt.
