종료하기 전에 자동으로 업데이트를 설치하는 방법은 무엇입니까?

Windows 7은 종료 전에 자동으로 업데이트를 설치합니다. Xubuntu에서 동일한 효과를 얻을 수 있습니까?

친구의 컴퓨터에 Xubuntu를 설치하고 보안 업데이트가 설치되어 있는지 확인하고 싶지만 컴퓨터를 잘 모르는 경우 업데이트 알림으로 인해 방해받지 않기를 바랍니다.

패키지가 unattended-upgrades설치되어 있는지 확인한 후 다음 옵션을 구성하십시오 /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";
