Probleme mit duplicity + GnuPG

[Florian Lindner <mailinglists@xgm.de>]

Hallo,

ich will ein Backup mit duplicity (Debian etch) machen:

osiris:~# duplicity --encrypt-key "F5DCE406" /home/flindner scp://flindner@bla.blubb.de 
/backup

SSH Login funktioniert ohne Password nur mit öffentlichen Schlüssel.  
Leider klappt wohl etwas anderes nicht. Zusätzlich habe ich noch die  
Frage, wie ich das Backup nur verschlüsseln, aber nicht signieren kann  
(also kein Passwort für GPG eingeben muss).

Ausgabe von obigen Kommando:

GnuPG passphrase:
Retype to confirm:
No signatures found, switching to full backup.
Traceback (most recent call last):

globals.backend)

in write
    def write(self, buf): return self.gpg_input.write(buf)
IOError: [Errno 32] Broken pipe
close failed: [Errno 32] Broken pipe

etwas anders, aber ähnlich ist der Fehler, wenn ich das SSH Protokoll  
anstelle von SCP:

osiris:~# duplicity --encrypt-key "F5DCE406" /home/flindner ssh://flindner@h700716.serverkompetenz.net/backup
GnuPG passphrase:
Retype to confirm:
No signatures found, switching to full backup.

  File "/usr/bin/duplicity", line 142, in full_backup
    bytes_written = write_multivol("full", tarblock_iter,  
globals.backend)
  File "/usr/bin/duplicity", line 78, in write_multivol
    globals.gpg_profile)
  File "/usr/lib/python2.4/site-packages/duplicity/gpg.py", line 217,  
in GPGWriteFile
    to_gpg_fp.write(data)

Danke!
