我第一次在 ubuntu 上设置 UPS。我完全按照这里的说明进行操作：https://www.sobyte.net/post/2023-03/ups-nut-configuration-tutorial/
我的 UPS 是 PowerShield Defender 650。
正确的驱动程序是“blazer_usb”。
我已命名该设备屏蔽和命令如
upsc pshield
工作正常。
系统日志还显示系统确实可以识别电池电源何时被激活。例如：
01/12/2024 9:43:20 PM
Jan 12 21:43:19 barbelith upsmon[2624]: UPS pshield@localhost on battery
01/12/2024 9:43:20 PM

01/12/2024 9:43:20 PM

01/12/2024 9:43:20 PM
Jan 12 21:43:19 barbelith upssched[154700]: exec_cmd(/opt/scripts/upssched-cmd.sh onbattnoti) returned 1
01/12/2024 9:43:30 PM
Jan 12 21:43:29 barbelith upssched[154701]: Event: onbattwarn
01/12/2024 9:43:30 PM
Jan 12 21:43:29 barbelith upssched[154701]: exec_cmd(/opt/scripts/upssched-cmd.sh onbattwarn) returned 1
01/12/2024 9:43:45 PM
Jan 12 21:43:44 barbelith upssched[154701]: Timer queue empty, exiting
但实际的脚本（/opt/scripts/upssched-cmd.sh）似乎没有运行。即，系统没有关闭。 我怎样才能解决这个问题？
