[Duplicity-talk] GPG error when backing up - invalid option "--pinentry-mode=loopback"

[Scott Classen]

Hello,

Using installed duplicity version 0.7.11, python 2.7.11, gpg 2.0.14 (Home: 
~/.gnupg), awk 'GNU Awk 3.1.7', grep 'grep (GNU grep) 2.20', bash 
'4.1.2(2)-release (x86_64-redhat-linux-gnu)'.

[snip]

GPGError: GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: invalid option "--pinentry-mode=loopback"



the GPG_OPTS variable in my duply conf file is empty. 

What should I do? is there a way to NOT pass the --pinentry-mode=loopback 
option to gpg?

Thanks,
Scott
