With app-backup/obnam-1.18.2 it is not possible any more to backup to an sftp:// target (at least, I did not test other configurations). Other operations like "generations" "ls" etc, fail with the same messages martin@bln9716n ~ $ obnam --config /home/martin/.obnam.bln9716w.conf ls Traceback (most recent call last): File "/usr/lib64/python2.7/site-packages/cliapp/app.py", line 190, in _run self.process_args(args) File "/usr/lib64/python2.7/site-packages/obnamlib/app.py", line 207, in process_args cliapp.Application.process_args(self, args) File "/usr/lib64/python2.7/site-packages/cliapp/app.py", line 567, in process_args method(args[1:]) File "/usr/lib64/python2.7/site-packages/obnamlib/plugins/show_plugin.py", line 233, in ls self.traverse(self.show_hdr_ls, self.show_item_ls, args) File "/usr/lib64/python2.7/site-packages/obnamlib/plugins/show_plugin.py", line 184, in traverse self.open_repository() File "/usr/lib64/python2.7/site-packages/obnamlib/plugins/show_plugin.py", line 92, in open_repository clients = self.repo.get_client_names() File "/usr/lib64/python2.7/site-packages/obnamlib/fmt_6/repo_fmt_6.py", line 149, in get_client_names return self._client_list.list_clients() File "/usr/lib64/python2.7/site-packages/obnamlib/fmt_6/clientlist.py", line 78, in list_clients if self.init_forest() and self.forest.trees: File "/usr/lib64/python2.7/site-packages/obnamlib/fmt_6/repo_tree.py", line 63, in init_forest allow_writes=allow_writes) File "/usr/lib64/python2.7/site-packages/larch/forest.py", line 199, in open_forest check_size('key_size', key_size, BadKeySize) File "/usr/lib64/python2.7/site-packages/larch/forest.py", line 193, in check_size if keyname not in ns.get_metadata_keys(): File "/usr/lib64/python2.7/site-packages/larch/nodestore_disk.py", line 167, in get_metadata_keys self._load_metadata() File "/usr/lib64/python2.7/site-packages/larch/nodestore_disk.py", line 148, in _load_metadata data = self.journal.cat(self.metadata_name) File "/usr/lib64/python2.7/site-packages/larch/journal.py", line 162, in cat return self.fs.cat(filename) File "/usr/lib64/python2.7/site-packages/obnamlib/repo_fs.py", line 91, in cat data = self.fs.cat(filename) File "/usr/lib64/python2.7/site-packages/obnamlib/plugins/sftp_plugin.py", line 558, in cat f.prefetch() TypeError: prefetch() takes exactly 2 arguments (1 given) After some research, I found this problem described on https://aur.archlinux.org/packages/obnam/ "paramiko-1.16.0 appears to break this pacakge. ...

Hi Martin, please test the new -r1 ebuild and let me know if this fixes the issue. I applied the patch you mentioned in the bug.
Hello Marc, app-backup/obnam-1.18.2-r1 and dev-python/paramiko-1.16.0 work well together. I Will close this bug and continue to backup to sfto://<my_home_server>.... THX for the quick response!
