/dev/tty error

[Daniel Carrera]

Hello,

I'm trying to use gpg on a remote server (the server has a copy of my 
public key, a file is encrypted there and my client downloads it by 
HTTP). I'm getting the following error:

gpg: cannot open /dev/tty: No such device or address

This is a Linux box (Red Hat I think). Do you know what this error 
means? What can I do to fix it?

Thank you for your help.

Cheers,
Daniel.
