Unable to use extension remotely

Is gnupg installed on the remote system ?

Yes, installed and working fine:

sbrown@rorschach:~$ which gpg
/usr/bin/gpg
sbrown@rorschach:~$ gpg --version

I will check this scenario. Thanks.

Yesterday i used my extension under Raspbian and i had some troubles too.
Do you have an additional PIN or pass-phrase dialog for GnuPG installed ?
I installed the QT based PIN or pass-phrase entry dialog for GnuPG package.

Now I checked same remote situation and I get the same error as above.

I think this cannot work. My extension relies on the external presence of the pin or pass-phrase dialog. The gpg on the remote machine cannot start a pin-pass-phrase dialog on the local machine.

What do you think ?

A short test you can try

echo "test" | gpg --clear-sign --pinentry-mode loopback

which runs in the terminal and asks the pass-phrase on the terminal. This should work.
