Package: libexo-common Version: 4.16.0-1 Your package used to ship the conffile /etc/xdg/xfce4/helpers.rc, but no longer does include it. I presume this is done on purpose since the libexo-helpers package is also gone, yet the obsolete conffile remains on the system after upgrades.
Please refer to dpkg-maintscript-helper(1) and dh_installdeb(1) how to properly clean up obsolete conffiles. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable'), (101, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.4-nouveau (SMP w/2 CPU threads) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) libexo-common depends on no packages. libexo-common recommends no packages.
