gpg asks for password

[Jon]

Using Duplicity 0.7.01

Using the --encrypt-key [key] option should avoid being prompted for the password. I am getting a pinentry dialogue asking for the password (either with or without --use-agent).

This might be related to a recent upgrade to GnuPG 2.1, not sure.

It doesn't matter if I enter a correct or incorrect password (or even blank). It still proceeds to back up. My concern is that I want it to run automatically in the background but I can't with pinentry stopping the process.

FYI, you can solve this problem by
1. add "allow-loopback-pinentry" to ~/.gnupg/gpg-agent.conf
2. add "--gpg-options=--pinentry-mode=loopback" to duplicity command line options.

See https://wiki.archlinux.org/index.php/GnuPG#Unattended_passphrase for more detail.

This appears to do the trick.

Thanks!
