なぜそんなに多くの依存関係が一致しないのですか?どのようにインストールしますか?
答え1
問題は、誤った構成名が原因で発生します。編集しました/etc/apt/sources.list次のように
deb http://deb.debian.org/debian bullseye main
deb-src http://deb.debian.org/debian bullseye main
deb http://deb.debian.org/debian-security/ bullseye-security main
deb-src http://deb.debian.org/debian-security/ bullseye-security main
deb http://deb.debian.org/debian bullseye-updates main
deb-src http://deb.debian.org/debian bullseye-updates main
完璧に動作します。
