Bagaimana cara menginstal pembaruan secara otomatis sebelum shutdown?

Windows 7 secara otomatis menginstal pembaruan sebelum shutdown. Bisakah saya mendapatkan efek yang sama pada Xubuntu?

Saya ingin menginstal Xubuntu di mesin teman dan memastikan bahwa pembaruan keamanan diinstal, tetapi ia buta komputer, dan saya tidak ingin dia terus-menerus diganggu dengan pemberitahuan pembaruan.

Pastikan Anda memiliki paket yang unattended-upgradesdiinstal, kemudian konfigurasikan opsi berikut di /etc/apt/apt.conf.d/50unattended-upgrades:

// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
    "${distro_id}:${distro_codename}";
    "${distro_id}:${distro_codename}-security";
    "${distro_id}:${distro_codename}-updates";
    "${distro_id}:${distro_codename}-backports";
    "Canonical:${distro_codename}";
};

// This option allows you to control if on a unclean dpkg exit
// unattended-upgrades will automatically run 
//   dpkg --force-confold --configure -a
// The default is true, to ensure updates keep getting installed
Unattended-Upgrade::AutoFixInterruptedDpkg "true";

// Split the upgrade into the smallest possible chunks so that
// they can be interrupted with SIGUSR1. This makes the upgrade
// a bit slower but it has the benefit that shutdown while a upgrade
// is running is possible (with a small delay)
Unattended-Upgrade::MinimalSteps "true";

// Install all unattended-upgrades when the machine is shuting down
// instead of doing it in the background while the machine is running
// This will (obviously) make shutdown slower
Unattended-Upgrade::InstallOnShutdown "true";

// Do automatic removal of new unused dependencies after the upgrade
// (equivalent to apt-get autoremove)
Unattended-Upgrade::Remove-Unused-Dependencies "true";
