由于奇怪的依赖问题，无法安装 VLC 和其他程序 
The following packages have unmet dependencies:
 vlc : Depends: vlc-nox (= 2.1.4+git20150226+r54594+19+11~ubuntu14.04.1) but it is not going to be installed
       Depends: libsdl-image1.2 (>= 1.2.10) but it is not installable
       Depends: libtar0 but it is not installable
       Depends: libva-x11-1 (> 1.3.0~) but 1.0.15-4 is to be installed
       Depends: libva1 (> 1.3.0~) but 1.0.15-4 is to be installed
       Depends: libvlccore7 (>= 2.1.0) but it is not going to be installed
       Recommends: vlc-plugin-notify (= 2.1.4+git20150226+r54594+19+11~ubuntu14.04.1) but it is not going to be installed
       Recommends: vlc-plugin-pulse (= 2.1.4+git20150226+r54594+19+11~ubuntu14.04.1) but it is not going to be installed

我试过

  1. sudo apt-get install -f
  2. sudo apt-get update
  3. sudo apt-get upgrade
  4. sudo apt-get purge vlc vlc-nox libsdl-image1.2 libtar0 libva-x11-1 libva1 libvlccore7 vlc-plugin-notify vlc-plugin-pulse

但错误仍然存​​在。VLC 不是唯一的东西。我尝试安装的许多其他软件包都给出了类似的依赖性错误，最终我放弃了安装。

我已经使用 Ubuntu 一段时间了。我只是不明白为什么这种情况时有发生。请帮忙...

正如您在输出中看到的，apt-cache policy …有些包没有安装候选，但情况不应该如此。因此，快速搜索这里显示所有包都可以在 Universe 存储库中找到，例如包libsdl-image1.2。

在此处输入图片描述

添加存储库：

sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install vlc
