apport-collect crashes due to launchpadlib.errors.CredentialsFileError

Launchpadlib developers, do you have some advice what to do with this? Thanks in advance!

Hi,

I think you have to catch this error and treat it as "no credentials".

My bet is that the file is empty due to issues when writing. When
trying to read it isn't in the required format and so no credentials
can be gained, therefore it raises an error so that the caller can
do something about it if they like. Therefore I think it's part of
the interface.

Can you suggest a better way this could be handled?

Thanks,

James

James, you're right, it happens when the credentials file is empty.

$ echo > ~/.cache/apport/launchpad.credentials

$ apport-collect -p linux 412704

Apport can do something like:

if os.path.exists(self.auth) and os.path.getsize(self.auth) > 1:
    # use existing credentials

Right, thanks. I think the most user friendly way would be to delete the file and re-authenticate. It's in ~/.cache, after all.

This bug was fixed in the package apport - 1.9.2-0ubuntu1

---------------
apport (1.9.2-0ubuntu1) karmic; urgency=low

  * New upstream bug fix release:
    - apport-cli: Print the URL and ask whether to open a browser. In many
      situations (such as usage on a server through ssh), it's preferable to not
      open the browser on the reporting computer. Thanks to Matt Zimmerman for the
      initial patch! (LP: #286415)
    - general-hooks/generic.py: Collect important glib errors/assertions (which
      should not have private data) from ~/.xsession-errors (LP: #431807)
    - launchpad.py: Link hardware data submission key if it exists. (LP: #424382)
    - apport-cli: Fix crash with non-ASCII characters in prompts.
    - Fix "apport-bug symptomname" to actually work.
    - launchpad.py: Fix crash on invalid credentials file. Thanks to Marco
      Rodrigues for the initial patch! (LP: #414055)
  * man/apport-bug.1: Document APPORT_IGNORE_OBSOLETE_PACKAGES (cherrypicked
    from trunk), and APPORT_STAGING (Ubuntu specific change, since it's a
    launchpad backend specific variable).
  * bin/apport-bug: Ignore -p option when giving two arguments, to keep
    compatibility with current bug filing instructions. (LP: #356755)
  * debian/copyright: Update copyright year and fix GPL link, thanks Marco
    Rodrigues!
