如何在关机前自动安装更新?

Windows 7会在关机前自动安装更新。 我可以在Xubuntu上获得相同的效果吗?

我想在朋友的机器上安装Xubuntu,并确保安装了安全更新,但他是计算机文盲,我不希望他经常受到更新通知的困扰。

确保安装了unattended-upgrades软件包,然后在/etc/apt/apt.conf.d/50unattended-upgrades配置以下选项:

 // 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";
