ImportError: No module named apport.packaging_impl

[Martin Pool]

Binary package hint: apport

When I hit an exception in rdiff-backup (not caused by a bug, just out of space), I get this import error from apport:

Error in sys.excepthook:
Traceback (most recent call last):

If you do

  python -c 'from apport.packaging_impl import impl as packaging'

does that generate the same error? Could it be that the python-apport package wasn't configured properly at that time?

[Martin Pool (mbp)]

That works. It's either specific to the situation, or it's gone away by itself, maybe because of the package being update.

It just happened again:

This is quite inexplicable to me, I'm afraid. I committed trunk r1547 to paper over this (catch and abort on ImportError), to avoid disrupting other programs.

  * New upstream bug fix release:
    - data/general-hooks/generic.py: Check $HOME, not /home for enough space.
      (LP: #422658)
    - launchpad.py: Intercept httplib2.ServerNotFoundError as well, to avoid
      crashes when being offline. (LP: #396276)
    - apport-cli: Save reports with .apport extension instead of .txt. Thanks
      to Steve Beattie! (LP: #401983)
    - fileutils.py, likely_packaged(): Ignored crashes in /var, packages don't
      ship executables there, and it creates false positives. (LP: #414368)
    - packaging-apt-dpkg.py, get_modified_files(): Fix crash with empty lines.
      (LP: #408280)
    - packaging-apt-dpkg.py: Use installed version instead of candidate
      version where appropriate. This also fixes a crash where an obsolete
      package is not available any more. (LP: #423511)

      schema default. (LP: #422277)

    - launchpad.py: Talk to staging if $APPORT_STAGING is set.
    - launchpad.py: Explicitly supply content_type for addAttachment, current
      wadllib requires it now.
    - apport_python_hook.py: Paper over inexplicable import error.
      (LP: #348250)
    - apport_python_hook.py: Protect against nonexisting sys.argv.
      (LP: #418051)
    - apport/ui.py, load_report(): Check that report has ProblemType field.
      (LP: #198543)
    - ui.py: Fix handling of complete vs. reduced report size. (LP: #92653).
      This also fixes a race condition crash with os.path.getsize().
      (LP: #348137)
    - fi.po: Fix mistranslation of "&Cancel". (LP: #355303)
    - apport-{gtk,kde}: Check for having $DISPLAY at startup to avoid crashes.
      (LP: #411276)
    - report.py, add_gdb_info(): Fix race condition in unlink_core, thanks to
      Tommi Komulainen! (LP: #397945)
    - ui.py, load_report(): Robustify check whether program is still
      installed. (LP: #329184)
    - packaging-apt-dpkg.py, install_retracing_packages(): Install package for
      ExecutablePath/InterpreterPath if missing; this can happen with package
      hooks which reassing package
    - launchpad.py: Add a comment when marking a bug as a duplicate.
      (LP: #418871)
  * Move gdb dependency from apport to GUI packages to avoid pulling in gdb on
    Ubuntu server. Thanks to Steve Beattie! (LP: #354172)
  * ubuntu-bug: Fix handling of .crash file arguments, thanks to Marco
    Rodrigues for pointing this out! (LP: #422881)
  * debian/local/apport-collect: Set content_type and description, wadllib
    requires them now. (LP: #423512) Also drop the ASCII reencoding
    workaround, this doesn't seem to be necessary any more.
  * apport/hookutils.py, attach_conffiles(): Fix crash with obsolete
    conffiles. (LP: #412132)
  * debian/local/apport-collect: Do not upload data if the affected package
    isn't installed and there is no source package hook available either.
    (LP: #417277)
  * debian/local/ubuntu-bug: Accept .apport extension, too; thanks to Steve
