应在关机时运行的 Systemd 服务不会执行 bash 脚本

bash 脚本位于 /opt/CleanUp.sh

find /home/*/Downloads/* -type f -exec shred -uz {} \;
rm -r /home/*/Downloads/*
find /home/*/Documents/* -type f -exec shred -uz {} \;
rm -r /home/*/Documents/*
find /home/*/Pictures/* -type f -exec shred -uz {} \;
rm -r /home/*/Pictures/*
find /home/*/Videos/* -type f -exec shred -uz {} \;
rm -r /home/*/Videos/*
find /home/*/Music/* -type f -exec shred -uz {} \;
rm -r /home/*/Music/*
exit 0

/etc/systemd/system/CleanUp.service 中的 .service 文件

[Unit]
Description=CleanUp Service
DefaultDependencies=no
Before=halt.target shutdown.target reboot.target

[Service]
Type=oneshot
ExecStart= /opt/CleanUp.sh
TimeoutStartSec=0

[Install]
WantedBy=halt.target shutdown.target reboot.target

脚本在关机时不执行。当我尝试通过以下方式启动它时

sudo service CleanUp start

我收到这个错误
