show what has been changed in a new version of a Debian package Using apt-listchanges

apt-listchanges is a tool to show what has been changed in a new version of a Debian package, as compared to the version currently installed on the system.

It does this by extracting the relevant entries from both the NEWS.Debian and changelog[.Debian] files, usually found in /usr/share/doc/package,from Debian package archives.

Given a set of filenames as arguments (or read from apt when using --apt), apt-listchanges will scan the files (assumed to be Debian package archives) for the relevant changelog entries, and display them all in a summary, sorted by urgency.

Install apt-listchanges in debian

#apt-get install apt-listchanges

apt-listchanges Syntax

apt-listchanges [options] {--apt | filename.deb …}

Configuration file located at /etc/apt/listchanges.conf

Example configuration file




The above configuration file specifies that in command-line mode, the default frontend should be “pager”. In apt mode, the xterm-pager frontend is default, a copy of the changelogs (if any) should be emailed to root, and apt-listchanges should ask for confirmation.If apt-listchanges is invoked with --profile=custom, the browser frontend will be used, and invoke mozilla.

This can be configured with the following command

#dpkg-reconfigure apt-listchanges
