[Bug 824708] [NEW] aptitude can no longer show changelogs: "Changelog download failed: Download queue destroyed." Please merge the fixed version, 0.6.8, from Debian.

You have been subscribed to a public bug by Daniel Hartwig (wigs):

Aptitude (<< 0.6.8) can't download/view package changelogs with
libapt-pkg (>= 0.8.16~exp3).  This affects both the command line
interface and the interactive (ncurses) interface.

Viewing a packages changelog is a significant part of deciding which
updates to apply.  Although the changelogs can still be viewed using
apt-get, it is a great inconvenience to no longer be able to do this
from aptitude's interactive interface.

[Test Case]

* An unrelated issue in aptitude requires deb-src lines to fetch
  changelogs from the command line. Ensure the system has some valid
  deb-src lines:

  $ sudo echo "deb-src http://archive.ubuntu.com/ubuntu/ precise main" >> /etc/apt/sources.list
  $ sudo apt-get update
  […]

* Choose a package, say python-apt, and verify the changelog is
  available with apt-get:

  $ apt-get changelog python-apt
  Get:1 Changelog for python-apt (http://changelogs.ubuntu.com/changelogs/pool/main/p/python-apt/python-apt_0.8.0ubuntu7/changelog) [109 kB]
  Fetched 109 kB in 0s (370 kB/s)

* Attempt to fetch the same changelog using aptitude:

  $ aptitude changelog python-apt
  Err Changelog of python-apt
  E: Changelog download failed: Download queue destroyed.
  E: Couldn't find a changelog for python-apt

[Regression Potential]

Small.

* Moderate size patch which is mostly trivial updates of types to
  unsigned long long as used in libapt-pkg.

* The updated module is only used to acquire changelogs[1], so any
  regression is likely to be limited to interacting with changelogs.

* Fixed in Debian sid since June with no regressions reported.

[1] The module is also used to acquire screenshots by the experimental
    GTK+ interface which is no longer developed and was never
    considered supported by upstream.
