Description Nicolas Pomarède 2014-08-22 14:25:28 CEST

Description of problem:

When trying to sync files with duplicity on a remote server using sftp or ssh protocol, there's an error :

eg : duplicity test_dir ssh://user@some_ip/backup/duplicity

Import of duplicity.backends.dpbxbackend Failed: No module named dropbox
BackendException: Could not initialize backend: No module named paramiko

The import of dropbox is harmless if you don't use dropbox in the url.
But the lack of paramiko module prevents from using ssh/sftp and duplicity will exit.

Installing python-paramiko manually solves the problem.

As duplicity already requires openssh-client, a require for "python-paramiko" should be added too.

Problem might be present too in cauldron version 0.6.24

Reproducible: 

Steps to Reproduce:

Comment 1 Philippe Makowski 2014-08-22 15:47:11 CEST

Advisory:
========================

Updated duplicity  package to fix a missing dependency:

the lack of paramiko module prevents from using ssh/sftp and duplicity will exit.

Comment 2 Rémi Verschelde 2014-08-23 13:54:31 CEST

Does that fix the bug for you Nicolas?

I tried it but I seem to hit a paramiko bug: https://github.com/paramiko/paramiko/issues/220
It might also be that I'm not using duplicity correctly though.

Comment 3 Nicolas Pomarède 2014-08-25 11:59:23 CEST

Under mageia4, installing python-paramiko fixes the problem.

I also removed all packages from main and installed duplicity-0.6.22-5.mga4.i586.rpm from core / update_testing and it correctly installed python-paramiko. Backups with duplicity worked correctly.

for #2, I think your problem is more related to ssh and your keys on the remote host than to duplicity itself, I don't have this error message.

For me, rpm can go from testing to main update.

BTW, I see cauldron suggests python-dropbox. Maybe it could be added to mageia4 too ? It's not really a bug fix, but I guess dropbox is often used as a backup media and mageia 4 doesn't have the python-dropbox rpm.

Comment 4 Samuel Verschelde 2014-09-04 10:47:27 CEST

In mga4 64, installing is fine, pulls the needed deps, and rpmdiff shows there's no other change than that added dep, so validating.
