Debian 8下安装VLC时遇到如下错误。请教各位该如何处理？

sudo apt-get -f install

同样的错误信息，无法安装。
原因好像是我之前加了deb-multimedia的源。

我刚在centos下无法安装mplayer，然后乱七八糟装了一堆，虽然mplayer没装上，但是能看视频了，我也是醉了。。。

这种问题我在ubuntu卸载libreoffice装Openoffice遇到过，也是apt-get -f install没用。
你这种错误是需要新版本的依赖文件却有老版本的文件，要用dpkg命令先卸载掉那3个老的依赖文件，然后再安装apt安装新软件。

试试：
$ sudo dpkg -l |grep vlc
然后全部卸了
$ sudo dpkg --purge vlc.....
一个一个删了，貌似dpkg不支持*匹配一次全部删除
删完了再apt-get 安装。

看看 aptitude 给出什么解决方案？

通过aptitude解决了。谢谢。
