Installation problem with gpg

I want to evaluate nocat for our hotspot. I install nocat in a Ubuntu
5.10 (kernel 2.6), Apache2. Gateway and Authservice in the same machine
to make some test. 

When I connect in my hotspot network I get the login page and after
login I recibe an error. I can see in Apache error log:  

 

[2005-12-07 18:04:46] User pruebas from 10.0.0.49 requests form

[2005-12-07 18:04:46] gpg --sign --armor
--homedir=/usr/local/nocat/authserv/pgp --keyring trustedkeys.gpg
--no-tty -o- returned error message:

gpg: Sorry, no terminal at all requested - can't get input

 

Any ideas? Please, I am stoped at this step. 

 

Thanks in advance.
