Compute engine - Not able to run startup script

[Rohith Kodiyath]

I am not able to run startup script . Getting the following error

`

systemd[1]: google-startup-scripts.service: Main process exited, code=exited, status=1/FAILURE

systemd[1]: google-startup-scripts.service: Failed with result 'exit-code'

systemd[1]: Failed to start Google Compute Engine Startup Scripts.

`

and my startup script

`

#! /bin/bash
apt-get remove --auto-remove sshguard
apt-get purge --auto-remove sshguard

`

Instance Image : ubuntu-1804-bionic-v20190722a

Am I doing something wrong ?. Added the startup script in the metadata and restarted the instance.

Note: I am not able to run browser SSH due to some issue. To debug the issue I am trying to disable the 'sshguard' service in the instance

Thanks
