Help! Please with decryption failed: No secret key (gpg in batch mode)

[Schrago, Gerard]

 Hi all,

Sorry to insist but I really need someone that can answer my question.
Why a running process cannot decrypt a file while the very same shell script invoked within a ssh session does it?
Please!

With my best regards.
Gerard.

Hi all,

Help needed in the following issue; I hope not to bother anyone but I need an advise from an expert.
If the verbose provided by the --debug-level guru would be of some help I can send it in a further mail.

I have to use GnuPG in batch mode to enable a running process to decrypt encrypted file.
If I run the shell script through ssh (with the specific user that was previously used to set the keys and has its proper .gnupg directory) this works fine despite the following warning:
WARNING: message was not integrity protected.
But if I have the running process invoking the very same script, the response is:
gpg: encrypted with RSA key, ID 911633C3
gpg: decryption failed: No secret key
I have then tried to modify the script to define home directory using --homedir and I got the following:
gpg: WARNING: unsafe permissions on homedir `/home/superagt/'"
gpg: keyring `/home/superagt//secring.gpg' created
gpg: keyring `/home/superagt//pubring.gpg' created
gpg: encrypted with RSA key, ID 911633C3
gpg: decryption failed: No secret key
It is to note that I see neither in /home/superagt/ nor in /home/superagt/.gnupg/ the secring.gpg pubring.gpg announced.
Thanks per advance for your help and support.

With my best regards.
