IOError: GnuPG exited non-zero, with code 2

Same problem here after trying an incremental backup after a full backup.

In my environment, it seems the PASSPHRASE variable is not recognized.

Debugging:
strace -s 128 -f duplicity .... > xy
grep GNUPG < xy

gives:
[pid 15476] write(4, "[GNUPG:] ENC_TO 37105F933226F 16 0\n"..., 38) = 38
[pid 15476] write(4, "[GNUPG:] USERID_HINT 37105F9C3216F backup key <email address hidden>\n"..., 99) = 99
[pid 15476] write(4, "[GNUPG:] NEED_PASSPHRASE 37105F9C3216F 62E7B190B96DE 16 0\n"..., 64) = 64
[pid 15476] write(4, "[GNUPG:] MISSING_PASSPHRASE\n"..., 28) = 28

[pid 15476] write(4, "[GNUPG:] BEGIN_DECRYPTION\n"..., 26) = 26
[pid 15476] write(4, "[GNUPG:] DECRYPTION_FAILED\n"..., 27) = 27
[pid 15476] write(4, "[GNUPG:] END_DECRYPTION\n"..., 24) = 24
[pid 15469] read(4, "[GNUPG:] ENC_TO 37105F9C3216F 16 0\n[GNUPG:] USERID_HINT 37105F9C3216F backup key <dustbin@headiss"..., 4096) = 347

Hope that hint helps.

It's not clear to me where actually the PASSPHRASE variable gets evaluated.
In the sources of duplicity (/usr/share/pyshared/duplicity) I cant find a hint on it.

Okay I got some resolution.

It works for me if I pass on the passphrase in a file, e.g.
by adding the parameter " --gpg-options --passphrase-file=/tmp/passphrase"

Best,

Jens

Jaunty is using an older version of duplicity, 0.5.09-0ubuntu2, and
duplicity is at 0.5.18. Please go to http://duplicity.nongnu.org/ and
download the most recent version.

I'll see what I can do to get the baseline updated.

Hi Jens,

Great, that seems to solve my problem... thanks a lot!

Kenneth: tried with the latest version but got error "unable to import gnupginterface".

Chris.

Grmbl, now consistently fails with another error... I'll raise separate bug report once I investigated a bit. Everything worked perfectly before Jaunty upgrade :-/

Grabbed the latest version in Debian unstable and everything works again as expected. Please consider upgrading this package in Jaunty as people might not be aware that their backup is failing silently since they upgraded...

This bug was fixed in the package duplicity - 0.5.18-0ubuntu1

---------------
duplicity (0.5.18-0ubuntu1) karmic; urgency=low

  * New upstream release (LP: #390666)
  * Fixes LP: #368062 and LP: #379648

Could you release the fix for jaunty, too? duplicity is broken and unusable this way.

Yes, please update for jaunty too!

In the meantime I installed the package from Karmic:
Go to http://packages.ubuntu.com/karmic/i386/duplicity/download and get duplicity*.deb
sudo dpkg -i ~/Desktop/duplicity*.deb

Seems to be working just fine here. This has the advantage over downloading and installing from source that in two years, when the version in ubuntu's mirrors move beyond the version in karmic, I'll pick that up too..

One can also use the latest and greatest with
https://launchpad.net/~duplicity-team/+archive/ppa
but then I was bitten by:
