Duplicity

cannot import name Gio

Asked by Dan Jaenecke

Hi,

I am using duplicity via deja-dup to create backups; but recently it stopped working, stating "BackendException: Hintergrundprogramm konnte nicht initialisiert werden: cannot import name Gio" (sorry for the german error messages, unfortunately I failed to switch to english messages).

The command causing this error (reduced to the minimum):

$ duplicity --gio collection-status file:///tmp
…
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1532, in <module>
    with_tempdir(main)
  File "/usr/bin/duplicity", line 1526, in with_tempdir
    fn()
  File "/usr/bin/duplicity", line 1364, in main
    action = commandline.ProcessCommandLine(sys.argv[1:])
  File "/usr/lib/python2.7/dist-packages/duplicity/commandline.py", line 1108, in ProcessCommandLine
    globals.backend = backend.get_backend(args[0])
  File "/usr/lib/python2.7/dist-packages/duplicity/backend.py", line 223, in get_backend
    obj = get_backend_object(url_string)
  File "/usr/lib/python2.7/dist-packages/duplicity/backend.py", line 211, in get_backend_object
    raise BackendException(_("Could not initialize backend: %s") % str(sys.exc_info()[1]))
BackendException: Hintergrundprogramm konnte nicht initialisiert werden: cannot import name Gio

Removing --gio from the command fixes the problem, but since the command is created by deja-dup I have no idea how to get rid of that option.

A possible solutions I found was that the package python-gi might be missing; it was already installed, and even a
$ apt install --reinstall python-gi
did not help.

My OS: Ubuntu 16.04.3 LTS
Version of duplicity: 0.7.06

I'd really appreciate any help…

regards
Dan

Hi,
thanks for the suggestion.
Unfortunately it did not solve my problem. python-gobject-2 was already installed, and adding python-gobject-2-dev did not help.

Are there any messages similar to
"Import of ... failed/succeeded"
in the log (before to your error messages)?

Strange. At the beginning it tells "Import von duplicity.backends.giobackend Succeeded" and later it got a problem with it.

I am sorry, but I am running out of ideas.

I suggest that you create a bug report.

hey Dan,

please update to the latest 0.7.16 from tarball or ppa (see http://duplicity.nongnu.org/). it should show more details on import errors.

make sure that deja-dup is run with python 2.7.

Dan,

can you check if the gio files
  https://packages.ubuntu.com/xenial/amd64/python-gi/filelist
exist on your box?

would you be willing to patch your duplicity to have it describe the error in more detail?

i see you are running duplicity in shell. in case you are willing to waive the comfort of deja-dup (which insists on gio) you could use the standard backends. note the additional given default python libs path and the missing '--gio'

  PYTHONPATH=/opt/duplicity/lib/python2.7/site-packages:/usr/lib/python2.7/dist-packages/ /opt/duplicity/bin/duplicity --verbosity=9 --gio collection-status file:///tmp

Hi edso and Manfred,

thanks for trying to help…

@edso:
all files from https://packages.ubuntu.com/xenial/amd64/python-gi/filelist exist.

Yes, I could path duplicity, but I most warn you that I am not really into python ;)
And yes, I *could* stop using deja-dup, but it is really convenient and I'd prefer to continue using it. For the moment I fixed the problem by having a shell-wrapper for duplicity which discards the --gio-Parameter.

@ Manfred
$ sudo updatedb
<no output>

$ locate Gio.py
/usr/lib/python2.7/dist-packages/gi/overrides/Gio.py
/usr/lib/python2.7/dist-packages/gi/overrides/Gio.pyc
/usr/lib/python3/dist-packages/gi/overrides/Gio.py
$ locate gio.x86_64-linux-gnu.so

nifty trick ;).. and oh so easy! so are you satisfied by your workaround or are you willing to dig deeper into why gio fails?

If you do:

$ python
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import Gio
>>> ^D

You should see no errors. If so, what do you get?
