在ubuntu 14.04上安装vlc时无法满足依赖性

Question

花了大约4小时现在仍然无法弄清楚这里有什么问题.

这是终端转储:

machine@machine:~$ sudo apt-get install vlc

我正在使用ubuntu 14.04(可靠),我几乎尝试了一切,但无法解决这些依赖关系

问题是对于不可用的库显示依赖关系.请帮助解决此问题.谢谢!

PS:我的askubuntu帐户不适用于某些后端帐户不匹配,这就是为什么我问SO

显然有一些第三方PPA安装,我使用终端下面的命令解决了:

删除第三方PPA

sudo rm /etc/apt/sources.list.d/mc3man-trusty-media-trusty*

然后删除为VLC添加的PPA(如果有的话)

sudo rm /etc/apt/sources.list.d/videolan-master-daily*

更新

sudo apt-get update

安装VLC:

sudo apt-get install vlc

参考:链接

然后我偶然发现了另一个问题,VLCSub(VLC字幕下载器的内置实用程序)在这个版本的VLC中没有工作,所以我删除了上面所有已安装的东西:

sudo apt-get purge vlc

然后为VLCSub兼容的VLC运行这些命令(这已过时,请参阅下面的编辑)

sudo add-apt-repository ppa:djcj/vlc-stable sudo apt-get update sudo apt-get install vlc

参考:链接

编辑(2015年7月7日更新)

所以,djcj/vlc-stable是注定要失败的,这是我在我的最新的Ubuntu安装如何更新的14.04:

对于2.2.1版

sudo apt-get remove vlc vlc-plugin-*  #remove any vlc data /  plugin

sudo add-apt-repository ppa:mc3man/trusty-media

sudo apt-get update

sudo apt-get install vlc vlc-plugin-*

参考:链接

..... 不要忘记添加VLSub以获得愉快的字幕下载体验 :)

Answer 2

我正在使用ppa:djcj/vlc-stable,但似乎已经消失了.最后几个软件更新抱怨它无法找到文件.

我删除了这个PPA,并尝试了一些我使用Google搜索找到的其他PPA,但没有任何效果.我一直得到与上面相同/类似的错误.

我终于尝试了以下命令:

sudo apt-get purge vlc-* # include the hyphen

它成功删除了vlc数据.之后,我能够使用以下命令安装和运行VLC:

sudo add-apt-repository ppa:videolan/stable-daily
sudo apt-get update
sudo apt-get install vlc

希望有所帮助.
