無人アップグレードが実行されていない、/ etc / cron.daily / aptがない

automatic-upgradesをインストールして構成しましたが、チェックするとインストールを待機しているセキュリティ更新プログラムが常に存在するため、実行されないようです。

https://help.ubuntu.com/community/AutomaticSecurityUpdates は、/etc/cron.daily/aptがautomatic-upgradesが機能するメカニズムであることを暗示しているようです。ただし、/etc/cron.daily/aptがありません。

dpkg -Sは、aptがそのファイルを所有していることを示します。

/etc/cron.daily/aptがないとunattended-upgradesが実行できなくなることを修正できますか？もしそうなら、どのように作成しますか？

（ このUbuntuフォーラムの投稿 で証明されているように、この問題を抱えているのは私だけではありません。残念ながら、解決策はありません。）

10.04サーバーでも同じ問題が発生します。無人アップグレードをインストールしましたが、/etc/cron.daily/aptはありません。

/etc/cron.daily/aptを古いインストールから新しいインストールにコピーしました：

私が知る限り、ファイルは.debにありません-パッケージングエラーです。これをパッケージャーの注意を喚起する方法をまだ考えていません
