Can't create Release.gpg file

[Jettana Mutchakwang]

Hello All,

First,I am apologize if this list that not for ask this question.I try
to remastering ubuntu install cd.I try to use this command :

  #  gpg --secret-keyring
/home/project/cdimage/secret/dot-gnupg/secring.gpg --keyring
/home/project/cdimage/secret/dot-gnupg/pubring.gpg --default-key
FBB75451  --no-options --batch --no-tty --armour  --detach-sign <
Release > Release.gpg

But it had error message :

gpg: no default secret key: secret key not available
gpg: signing failed: secret key not available

After that I change keysign to my gpg key by :

#  gpg --secret-keyring
/home/project/cdimage/secret/dot-gnupg/secring.gpg --keyring
/home/project/cdimage/secret/dot-gnupg/pubring.gpg --default-key
0368BBF8  --no-options --batch --no-tty --armour  --detach-sign <
Release > Release.gpg

and it had error again like this :

gpg: can't query passphrase in batch mode
gpg: no default secret key: bad passphrase
gpg: signing failed: bad passphrase

After that I remove "--batch --no-tty" option that work.

#  gpg --secret-keyring
/home/project/cdimage/secret/dot-gnupg/secring.gpg --keyring
/home/project/cdimage/secret/dot-gnupg/pubring.gpg --default-key
0368BBF8  --no-options  --armour  --detach-sign < Release >
Release.gpg

but when I burn my remastering install cd that fail at configure apt step.
I look in /var/log/syslog that had error message like this :
