启动网络服务后，无法在systemd中启动Activation.service

我有一个Activation.service ，我希望在网络服务成功启动后在启动期间执行。 这是Activation.service文件：

 [Unit] Description=Starting activation service during boot Wants=network-online.target After=network-online.target [Service] Type=forking ExecStart=/opt/Neurotec_Biometric_10_0_SDK/Bin/Linux_x86_64/Activation/run_pgd.sh TimeoutSec=30 Restart=on-failure RestartSec=10 StartLimitInterval=350 StartLimitBurst=10 [Install] WantedBy=multi-user.target Alias=Activation.service 

run_pgd.sh脚本工作正常，我在加载systemd之前测试了该脚本。

但是sudo systemctl start Activation.service会抛出错误。 这是我从systemctl status Activation.service获得的systemctl status Activation.service

 ● Activation.service - Starting activation service during boot Loaded: loaded (/etc/systemd/system/Activation.service; disabled; vendor preset: enabled) Active: activating (auto-restart) (Result: exit-code) since Thu 2017-11-23 09:46:30 IST; 3s ago Process: 3015 ExecStart=/opt/Neurotec_Biometric_10_0_SDK/Bin/Linux_x86_64/Activation/run_pgd.sh (code=exited, status=1/FAILURE) Nov 23 09:46:30 inch-desktop systemd[1]: Failed to start Starting activation service during boot.

这个日志来自journalctl -xe

我不确定出了什么问题。 有什么我需要做的
