Source: xine-ui Version: 0.99.9-1.1 Severity: serious Hi,
The libxine2-ffmpeg, libxine2-misc-plugins and libxine2-x packages have a trigger cycle via the xine-ui package. This was detected by a script on jenkins.debian.net[1]. Steps to reproduce the cycle (in a Jessie/sid chroot): """ apt-get install xine-ui libxine2-ffmpeg dpkg --unpack /var/cache/apt/archives/libxine2-ffmpeg_*.deb dpkg --configure --pending """ (Similar for the other libxine2-* binaries) This simulates an upgrade scenario, where libxine2-ffmpeg might be temporarily deconfigured while xine-ui remains configured. If this happens, dpkg is unable to recover as the cycle due to "await" trigger AND the dependency requires both packages to be configured. Known solutions: * Use no-await triggers. *CAVEAT*: not always applicable. Known suitable use cases includes "cache" handling, where the cache is allowed to be out of date tempoarily. * Reduce the dependency to Recommends. *CAVEAT*: Rarely applicable. * Rewrite the solution to avoid triggers entirely. *CAVEAT*: May be non-trivial and likely to involve updates to all packages relying on the trigger. ~Niels [1] https://jenkins.debian.net/view/Warnings/job/dpkg_sid_find_trigger_cycles/32/console -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
