[Bug 1353171] Re: Misparses dpkg status line, fails to write apport reports

[Launchpad Bug Tracker]

This bug was fixed in the package apt - 1.0.1ubuntu2.6

---------------
apt (1.0.1ubuntu2.6) trusty-proposed; urgency=medium

  * apt-pkg/deb/dpkgpm.cc:
    - update string matching for dpkg I/O errors. (LP: #1363257)
    - properly parse the dpkg status line so that package name is properly set
      and an apport report is created. Thanks to Anders Kaseorg for the patch.

Title:
  Misparses dpkg status line, fails to write apport reports

Status in “apt” package in Ubuntu:
  Fix Released
Status in “apt” source package in Trusty:
  Fix Released

Bug description:
  Test Case
  ---------
  1) sudo apt-add-repository ppa:daisy-pluckers/daisy-seeds
  2) sudo apt-get update
  3) sudo apt-get install crash-in-postinst
  4) observe a package installation failure dialog

  With the version of apt in the archive you will *not* receive a crash
  file in /var/crash. If you install the version of apt from -proposed
  you should receive a crash file in /var/crash and an apport dialog
  should appear.

  For a while apt has not been writing apport reports for dpkg
  maintainer script errors. Here’s why:

  • pkgDPkgPM::ProcessDpkgStatusLine sees a line like
  "status: cyrus-clients : error : subprocess installed post-installation script returned error exit status 1".
  • StringSplit splits it into
  list == {"status", "cyrus-clients ", "error ", "subprocess installed post-installation script returned error exit status 1"}.
  • pkgname is set to Strip(list[1]) == "cyrus-clients".
  • However, the original list[1] == "cyrus-clients " (with a trailing space) is passed to WriteApportReport.
  • WriteApport fails to find "cyrus-clients " in the cache, and bails out.

  Patch attached.
