Gotcha!

I skimmed through the backup script and there was it: --gpg-options "--pinentry-mode loopback

Supplying this option to the restore command solved my issue. Thank you very much for the help! I would have searched for this for days. :)

Best regards,
Mate

i am surprised duplicity backs up for you w/ gpg 2.1 .. gpg changed
some stuff and you should need extra parameters for it to work
properly (maybe just for decrypting though). check here
 http://sourceforge.net/p/ftplicity/bugs/76/

do you use duply or plain duplicity?

Dear Edger,

thank you for the quick reply! I was able to encrypt and decrypt a file using the given key.

The key was greated with GnuPG 1.4 but now I am using 2.1. The version of Duplicity is 0.6.25.

Best regards,
Mate

Hi,

I know it might be a GnuPG issue but I sincerely hope that someone on this list might have a solution for me. :)

So I am trying to restore an ecrypted backup and receives the following error:

GPGError: GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: encrypted with 4096-bit RSA key, ID xxxxx, created 2011-02-24
"xxxx <address@hidden>"
gpg: public key decryption failed: Invalid IPC response
gpg: decryption failed: No secret key
===== End GnuPG log =====

The key is in the user's keyring, at least the gpg --list-secret-keys shows the ID. The password seems to be right beacuse I am using this key to encrypt my weekly backups. Does anyone have any suggestion on this? I am not really familiar with GnuPG.


ok,

first try manually en/decrypting something on the command line against
that key. see
http://www.dewinter.com/gnupg_howto/english/GPGMiniHowto-4.html#ss4.1

also,
1. what is your gpg version?
2. please send me the output of 'gpg --list-secret-keys' privately and
mention the keyid you effectively used to back up.
