我正在运行 Debian 9 Stretch。
我已经安装了以下包。
unattended-upgrades/stable,now 0.93.1+nmu1 all [installed]
我的20auto-upgrades文件如下：
# cat /etc/apt/apt.conf.d/20auto-upgrades
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";
我的50unattended-upgrades样子是：
# cat /etc/apt/apt.conf.d/50unattended-upgrades
// Unattended-Upgrade::Origins-Pattern controls which packages are
// upgraded.
//
// Lines below have the format format is "keyword=value,...". A
// package will be upgraded only if the values in its metadata match
// all the supplied keywords in a line. (In other words, omitted
// keywords are wild cards.) The keywords originate from the Release
// file, but several aliases are accepted. The accepted keywords are:
// a,archive,suite (eg, "stable")
// c,component (eg, "main", "contrib", "non-free")
// l,label (eg, "Debian", "Debian-Security")
// o,origin (eg, "Debian", "Unofficial Multimedia Packages")
// n,codename (eg, "jessie", "jessie-updates")
// site (eg, "http.debian.net")
// The available values on the system are printed by the command
// "apt-cache policy", and can be debugged by running
// "unattended-upgrades -d" and looking at the log file.
//
// Within lines unattended-upgrades allows 2 macros whose values are
// derived from /etc/debian_version:
// ${distro_id} Installed origin.
// ${distro_codename} Installed codename (eg, "jessie")
Unattended-Upgrade::Origins-Pattern {
// Codename based matching:
// This will follow the migration of a release through different
// archives (e.g. from testing to stable and later oldstable).
// "o=Debian,n=jessie";
// "o=Debian,n=jessie-updates";
// "o=Debian,n=jessie-proposed-updates";
// "o=Debian,n=jessie,l=Debian-Security";
// Archive or Suite based matching:
// Note that this will silently match a different release after
// migration to the specified archive (e.g. testing becomes the
// new stable).
// "o=Debian,a=stable";
"o=Debian,a=stable-updates";
"o=Debian,a=proposed-updates";
"origin=Debian,codename=${distro_codename},label=Debian-Security";
};
// List of packages to not update (regexp are supported)
Unattended-Upgrade::Package-Blacklist {
// "vim";
// "libc6";
// "libc6-dev";
// "libc6-i686";
};
// 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 "false";
// 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";
// Send email to this address for problems or packages upgrades
// If empty or unset then no email is sent, make sure that you
// have a working mail setup on your system. A package that provides
// 'mailx' must be installed. E.g. "[email protected]"
Unattended-Upgrade::Mail "root";
// Set this value to "true" to get emails only on errors. Default
// is to always send a mail if Unattended-Upgrade::Mail is set
//Unattended-Upgrade::MailOnlyOnError "true";
// Do automatic removal of new unused dependencies after the upgrade
// (equivalent to apt-get autoremove)
//Unattended-Upgrade::Remove-Unused-Dependencies "false";
// Automatically reboot *WITHOUT CONFIRMATION* if
// the file /var/run/reboot-required is found after the upgrade
//Unattended-Upgrade::Automatic-Reboot "false";
// Automatically reboot even if there are users currently logged in.
//Unattended-Upgrade::Automatic-Reboot-WithUsers "true";
// If automatic reboot is enabled and needed, reboot at the specific
// time instead of immediately
// Default: "now"
//Unattended-Upgrade::Automatic-Reboot-Time "02:00";
// Use apt bandwidth limit feature, this example limits the download
// speed to 70kb/sec
//Acquire::http::Dl-Limit "70";
// Enable logging to syslog. Default is False
// Unattended-Upgrade::SyslogEnable "false";
// Specify syslog facility. Default is daemon
// Unattended-Upgrade::SyslogFacility "daemon";
此时，如果我运行apt update，我可以看到：
# apt update
<skipping-output>
Reading package lists... Done
Building dependency tree
Reading state information... Done
52 packages can be upgraded. Run 'apt list --upgradable' to see them.
现在默认情况下，我/lib/systemd/system/apt-daily.timer有/lib/systemd/system/apt-daily-upgrade.timer
他们已经违约
# cat /lib/systemd/system/apt-daily.timer
[Unit]
Description=Daily apt download activities
[Timer]
OnCalendar=*-*-* 6,18:00
RandomizedDelaySec=12h
Persistent=true
[Install]
WantedBy=timers.target
和
# cat /lib/systemd/system/apt-daily-upgrade.timer
[Unit]
Description=Daily apt upgrade and clean activities
After=apt-daily.timer
[Timer]
OnCalendar=*-*-* 6:00
RandomizedDelaySec=60m
Persistent=true
[Install]
WantedBy=timers.target
但我想覆盖这些值。因此我创建了以下文件：
# cat /etc/systemd/system/apt-daily.timer.d/override.conf
[Timer]
OnCalendar=
OnCalendar=17:23
和
# cat /etc/systemd/system/apt-daily-upgrade.d/override.conf
[Timer]
OnCalendar=
OnCalendar=17:24
然后我重新启动了2个服务。
systemctl restart apt-daily unattended-upgrades.service
但无人值守升级没有运行。日志目录似乎为空：
# ls -tlrh /var/log/unattended-upgrades
total 0
-rw-r--r-- 1 root root 0 Dec 22 2017 unattended-upgrades-shutdown.log
有什么想法我可能错过了什么吗？
编辑
运行该命令journalctl --since yesterday -u apt-daily.service得到以下结果：

答案1
错误出现在这一行：
cat /etc/systemd/system/apt-daily-upgrade.d/override.conf
你可能从 debian 官方文档中复制了它https://wiki.debian.org/UnattendedUpgrades目前其中有一个错误，误导了很多人。它声称你可以通过创建一个名为的文件来覆盖升级时间
/etc/systemd/system/apt-daily-upgrade.d/override.conf
但正确的路径是
/etc/systemd/system/apt-daily-upgrade.timer.d/override.conf
添加后，请执行以下命令以确保其有效：
sudo systemctl daemon-reload
让它熟悉新创建的文件
sudo systemctl restart apt-daily-upgrade.timer
应用 override.conf
sudo systemctl status apt-daily-upgrade.timer
向您显示下一个计时器事件的安排时间正确）
如果您还编辑了下载时间：
sudo systemctl restart apt-daily.timer
sudo systemctl status apt-daily.timer
我通知了[电子邮件保护]由于我还不是那里的编辑，所以要么他们会修复它，要么我会修复它（如果他们授予我访问权限）。
