これがどのように発生したのか、どのように修正するのか私にはわかりません。gnupg、gnupg-agent、gnupg-pkcs11-scd、gnupg2、gnupg-curl、gnupg-pkcs11-scd-dbgがインストールされています。
私は失礼なことをしようとしているわけではありませんが、その前に「sudo」と入力していますか？したがって、「sudo apt-get update」が完全なコマンドになります。

エラー（E）、次に警告（W）に焦点を合わせます。それは言っていない「リポジトリが『http.kali.org/kaliカーリー・ローリングリリース』をもはや署名されています」。そのため、まだサポートされているかどうかを確認し、必要に応じてシグネチャを更新してください。それでもkali 1がある場合は、アップグレードすることをお勧めします。たとえば、こちらをお読みください。@FiZi sudoとは関係ないと思います。その場合はapt-getで警告する必要があります。
