无法解析包依赖性
This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. vlc: Depends: vlc-nox (= 2.2.0-1) but 2.2.0-1 is to be installed Depends: libavcodec-extra-56 (>= 6:11.2) but 6:11.2-1 is to be installed Depends: libavutil54 (>= 6:11~beta1) but 6:11.2-1 is to be installed Depends: libc6 (>= 2.16) but 2.21-0ubuntu4 is to be installed Depends: libegl1-x11 but it is a virtual package Depends: libfreetype6 (>= 2.2.1) but 2.5.2-2ubuntu3 is to be installed Depends: libgcc1 (>= 1:4.1.1) but 1:5.1~rc1-0ubuntu1 is to be installed Depends: libgles1 but it is a virtual package Depends: libgles2 but it is a virtual package Depends: libqtcore4 (>= 4:4.8.0) but 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu6.1 is to be installed Depends: libqtgui4 (>= 4:4.8.0) but 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu6.1 is to be installed Depends: libstdc++6 (>= 4.9) but 4.9.2-10ubuntu13 is to be installed Depends: zlib1g (>= 1:1.2.3.3) but 1:1.2.8.dfsg-2ubuntu1 is to be installed 我没有在这里或这里的PPA中使用它。
这些是我的软件来源：
sudo apt-get install --fix-missing （在sudo apt-get update ）的输出是：
The following packages were automatically installed and are no longer required: libafpclient0 linux-headers-3.19.0-23 linux-headers-3.19.0-23-generic linux-image-3.19.0-23-generic linux-image-extra-3.19.0-23-generic Use 'apt-get autoremove' to remove them. 0 to upgrade, 0 to newly install, 0 to remove and 24 not to upgrade.
使用Synaptic Package Manager，没有破坏的包：
