When this option is enabled, the daily script will execute <command>unattended-upgrade</command> (from the <emphasis role="pkg">unattended-upgrades</emphasis> package) which — as its name suggest — can automatize the upgrade process for some packages (by default it only takes care of security updates, but this can be customized in <filename>/etc/apt/apt.conf.d/50unattended-upgrades</filename>). Note that this option can be set with the help of debconf by running <command>dpkg-reconfigure -plow unattended-upgrades</command>. If <emphasis role="pkg">apt-listbugs</emphasis> is installed, it will prevent an automatic upgrade of packages which are affected by an already reported serious or grave bug.
عند تفعيل هذا الخيار، سوف يُنفِّذ السكربت اليومي الأمر <command>unattended-upgrade</command> (من الحزمة <emphasis role="pkg">unattended-upgrades</emphasis>) الذي يعمل (كما يدل اسمه) على تحديث بعض الحزم آلياً (يهتم هذا الأمر افتراضياً بالتحديثات الأمنية فقط، لكن يمكن تخصيصه عبر الملف <filename dir="ltr">/etc/apt/apt.conf.d/50unattended-upgrades</filename>). لاحظ أنه يمكن تفعيل هذا الخيار بمساعدة debconf عبر استدعاء الأمر <command>dpkg-reconfigure -plow unattended-upgrades</command>.
