What do the following commands give you? $ apt-cache policy ffmpeg libavcodec58 libavformat58 libavutil56 libswresample3 libc6 $ apt-mark showhold Also, do you have any package pins in /etc/apt/preferences or /etc/apt/preferences.d/* ? That said: dist-upgrade against sid is frequently a bad idea, and I am not at all surprised that you ran into issues. The usual comment about running sid is that "if anything breaks, you get to keep the pieces". The best recommendation as I understand matters is to have sources.list entries for both testing and sid, use /etc/apt/preferences to pin sid at a priority which will never be chosen by default, and then install items from sid selectively as needed. If this is a production system rather than primarily a test machine, you might be best served to reinstall, and this time not try to dist-upgrade against sid en masse. For myself, I have sources.list entries for stable and testing, and in the rare case that I need something from sid, modify sources.list long enough to 'apt-get update ; apt-get install [packagename]', then modify sources.list to its previous state and run 'apt-get update' again. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
