I'm seeing an error every time I do the command below. Why?

```
$crontab -l
no crontab for server

```

where *server* is the user account.

This issue comes about because the script in crontab doesn't work, so I've tried to break down the problem. This is what I have put in using `crontab -e`:

```
crontab -e
@reboot /usr/bin/teamspeak3-server_linux-amd64/ts3server_minimal_runscript.sh

```

I press ctrl + o and save it, reboot and find the script doesn't boot (even though the script itself does work if I double click it from the GUI). If I do a `crontab -l` after the reboot, I find I get the same error as above. Even before the reboot, if I try and open the `crontab -e` just after I saved this command inside of the file, the line of code isn't there.
