[Bug 1446537] Re: apport hook fails in add_info with TypeError: 'str' does not support the buffer interface

[Chris J Arges]

Hello Jean-Baptiste, or anyone else affected,

Accepted apport into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/apport/2.20.1-0ubuntu2.2 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Title:
  apport hook fails in add_info with TypeError: 'str' does not support
  the buffer interface

Status in apport package in Ubuntu:
  Fix Released
Status in apport source package in Xenial:
  Fix Committed

Bug description:
  Impact
  ------
  Some apport package hooks are not able to check the contents of log files for errors, e.g. looking for hard disk errors in ubiquity install logs, so we may be getting crash reports that we don't want.

  
  Test Case
  ---------
  ⟫ ubuntu-bug ubiquity
  dpkg-query: aucun paquet ne correspond à ubiquity
  ERROR: hook /usr/share/apport/package-hooks/source_ubiquity.py crashed:
  Traceback (most recent call last):
    File "/usr/lib/python3/dist-packages/apport/report.py", line 197, in _run_hook
      symb['add_info'](report, ui)
    File "/usr/share/apport/package-hooks/source_ubiquity.py", line 61, in add_info
      if 'Buffer I/O error on device' in syslog:
  TypeError: 'str' does not support the buffer interface

  With the version of the package in the archive you'll see the above
  Traceback, with the version of proposed you will not.

  Regression Potential
  --------------------
  The change uses a try, except clause to do the decoding of the log file so there should be little chance of a regression.
