无人值守升级的系统计时器

Question

我尝试使用systemd计时器配置无人值守升级，如所述

我配置的/etc/systemd/system/apt-daily-upgrade.timer.d/override.conf文件是这样的：

[Unit]
Description=Daily apt upgrade and clean activities
After=apt-daily.timer
[Timer]
OnCalendar=Mon,Wed,Fri 6:00
RandomizedDelaySec=60m
Persistent=true
[Install]
WantedBy=timers.target

当我检查下一次触发时，我得到：

# systemctl status apt-daily-upgrade.timer
● apt-daily-upgrade.timer - Daily apt upgrade and clean activities
Loaded: loaded (/lib/systemd/system/apt-daily-upgrade.timer; enabled; vendor preset: enabled)
Drop-In: /etc/systemd/system/apt-daily-upgrade.timer.d
└─override.conf
Active: active (waiting) since Wed 2020-03-11 13:23:17 UTC; 53min ago
Trigger: Thu 2020-03-12 06:31:32 UTC; 16h left

因此，它假设在下周四触发，而OnCalendar参数中没有定义Sous。

别看我错过了什么：/

感谢

发现，计时器是累积的，因此应重置现有计时器：

[Timer]
OnCalendar=
OnCalendar=Mon,Wed,Fri 6:00

它现在运行良好。
