Thanks - I'll do that. I'm using this machine for a series of jobs which will take me a week or two and for which I need VLC. Then I think it might be an idea to try a fresh install using the most recent ISO.kurotsugi wrote:the root of your problem is the epic battle libav vs ffmpeg on debian. debian is using libav but DMO is using ffmpeg. all DMO packages depends on ffmpeg to work (you'll need to install libavcodec-XX dmo version). libavcodec-extra-XX is part of debian, thus, it contain libav. if you're using DMO then you mustn't install libavcodec-extra-XX at all cost. however, for unknown reason UM issued a command to install libavcodec-extra-XX and broke your system.
the easiest solution would be avoid using UM until we solve the issue. else, you can try to use apt-pinning and give libavcodec-extra-XX (-1) priority so that it never installed into your system.
Fortunately none of those is currently essential (I used this machine to test out customizations of Kate when an earlier upgrade removed some Gedit plugins).anyway, vlc isn't the only thing broke on your system. you'll need to reinstall these packages to revert it to the previous states
I don't recall being invited to confirm anything (although I'm quite capable of contributing to problems when given the opportunity ). Wouldn't the gap before the 3rd command be how long it took to remove those packages ?if we look into the logs,Yes, I was wondering about that one as well.the small gap between 1st and 2nd command means that it was done by a kind of script (probably solydfixes. it tried to remove DMO but failed. the probabilities are: dave might accidentally use maintainance tool on UM to remove DMO or the UM have a problem and executed solydxkfixes.
