[Duplicity-talk] Fails to restore backup : AssertionError: [(('bin', 'gunzip') reg)] :-(

[Olivier Berger]

Hi.

( FYI, this is a copy of a bug report I've filed in Debian's BTS :
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572102 )

I've made backups using backupninja with duplicity backend.

I need to restore a filesystem after a crash of one machine, but cannot
do it since duplicity 0.6.06 (Debian package) seems to be failing :

# duplicity restore file:///mnt/xxxx/dupbackups/xxxxx_slash/ /xxxxx/ 
GnuPG passphrase: 
Local and Remote metadata are synchronized, no sync needed.
Last full backup date: Sat Jan  2 22:48:30 2010
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1236, in <module>
    with_tempdir(main)
  File "/usr/bin/duplicity", line 1229, in with_tempdir
    fn()
  File "/usr/bin/duplicity", line 1183, in main
    restore(col_stats)
  File "/usr/bin/duplicity", line 538, in restore
    restore_get_patched_rop_iter(col_stats)):
  File "/usr/lib/python2.5/site-packages/duplicity/patchdir.py", line 518, in 
Write_ROPaths
    for ropath in rop_iter:
  File "/usr/lib/python2.5/site-packages/duplicity/patchdir.py", line 491, in 
integrate_patch_iters
    final_ropath = patch_seq2ropath(normalize_ps(patch_seq))
  File "/usr/lib/python2.5/site-packages/duplicity/patchdir.py", line 458, in 
patch_seq2ropath
    assert first.difftype != "diff", patch_seq
AssertionError: [(('bin', 'gunzip') reg)]

Then it gets stuck and I can notice lots of GPG processes.

Any clue on how to solve this ?

Thanks in advance.

Best regards,
