Hello Faustin, I have added an unstable entry for wireguard according to the provided wiki entry https://wiki.debian.org/Wireguard which seems to cause this problem. When commenting everything out that was added to the following files, the installation seems to work.
/etc/apt/sources.list.d/unstable-wireguard.list /etc/apt/preferences.d/limit-unstable Can you tell me what I did wrong? Best regards, Mark
