Dear Maintainer,

On Debian 13 (trixie), running:

    python3 -m pip check

reports:

    apt-listchanges 4.8 requires debconf, which is not installed.

However, debconf and python3-debconf are both correctly installed:

    apt-listchanges: install ok installed 4.8
    debconf: install ok installed 1.5.91
    python3-debconf: install ok installed 1.5.91

The Python debconf module is also present and imports successfully:

    python3 -c 'import debconf; print(debconf.__file__)'

Output:

    /usr/lib/python3/dist-packages/debconf.py

In addition:

    sudo apt-get check

completes successfully without reporting broken Debian package dependencies.

The apparent cause is the Python package metadata of apt-listchanges.
apt-listchanges declares debconf as a Python distribution dependency, but
debconf is provided by Debian and is not installed as a normal PyPI
distribution with metadata that pip recognizes.

As a result, pip check reports debconf as missing even though the Debian
package and Python module are correctly installed.

Expected result:
pip check should not report debconf as missing when the Debian dependency
is correctly satisfied.

Actual result:
pip check reports:

    apt-listchanges 4.8 requires debconf, which is not installed.

Please consider adjusting the Python dependency metadata so that the
Debian-specific debconf dependency does not cause this false-positive
pip check result.

No local modifications have been made to the Debian Python packages or
their metadata.

We believe that the bug you reported is fixed in the latest version of
apt-listchanges, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1145641@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Changes:
 apt-listchanges (4.8.1) unstable; urgency=medium
 .
   * Remove debconf from pip dependencies in setup.py, since it's not
     actually a pip module. This fixes spurious warnings about
     apt-listchanges and debconf from `python3 -m pip check`.
     (Closes: #1145641)
 .
   * Load config file fragments in /etc/apt/listchanges.conf.d in file name
     order so they are loaded deterministically. Fix courtesy of Kenichiro
     Kakizaki. (Closes: #1150230)
