为什么我的 systemd 计时器已启用，但在重启或恢复后却处于非活动状态

为什么我的 systemd 计时器已启用，但在重启或恢复后却处于非活动状态

我已经创建了一个 SystemD 计时器来触发服务，但是虽然已启用，但在 PC 重启或恢复后，计时器并未启动：

$ sudo reboot
....AFTER reboot...
$ systemctl is-enabled ncc-record.timer
enabled
$ systemctl is-active ncc-record.timer
inactive
$ systemctl cat ncc-record.timer
# /usr/local/lib/systemd/system/ncc-record.timer
[Unit]
Description=Trigger the service record.service
[Timer]
OnCalendar=Sun *-*-* 11:29:30
[Install]
WantedBy=timers.target
$ systemctl status ncc-record.timer
○ ncc-record.timer - Trigger the service record.service
     Loaded: loaded (/usr/local/lib/systemd/system/ncc-record.timer; enabled; vendor preset: enabled)
     Active: inactive (dead)
    Trigger: n/a
   Triggers: ● ncc-record.service
$

EDIT0：我在计时器每个部分的最后一条指令后添加了一个换行符，并将计时器移入/lib/systemd/system/：

$ sudo mv -v /usr/local/lib/systemd/system/ncc-record.timer /lib/systemd/system/ncc-record.timer
copied '/usr/local/lib/systemd/system/ncc-record.timer' -> '/lib/systemd/system/ncc-record.timer'
removed '/usr/local/lib/systemd/system/ncc-record.timer'
$ sudo systemctl daemon-reload 
$ systemctl cat ncc-record.timer

EDIT1：我还添加了将服务移动到/lib/systemd/system/计时器的同一目录中（），问题解决了：）
