尝试使用libvlccore9解决PPA问题，导致程序包管理无法运行

因为PPA没有实际的bug跟踪器而且维护得非常糟糕，我想我会问这里如何解决这个问题。

vlc-master PPA中的软件包libvlccore9正在尝试安装/usr/lib/x86_64-linux-gnu/libvlccore.so.9.0.0 ，它应该由libvlccore8安装。

问题是为什么，libvlccore8没有显示该文件，

 apt-file show libvlccore8 libvlccore8: /usr/lib/x86_64-linux-gnu/libvlccore.so.8 libvlccore8: /usr/lib/x86_64-linux-gnu/libvlccore.so.8.0.0 libvlccore8: /usr/share/bug/libvlccore8/control libvlccore8: /usr/share/bug/libvlccore8/presubj libvlccore8: /usr/share/doc/libvlccore8/NEWS.Debian.gz libvlccore8: /usr/share/doc/libvlccore8/changelog.Debian.gz libvlccore8: /usr/share/doc/libvlccore8/copyright 

我有一个libvlccore8

 dpkg -l | grep -i libvlccore rc libvlccore7 2.1.6-0ubuntu14.04.1 amd64 base library for VLC and its modules ii libvlccore8:amd64 3.0.0~~git20171208+r73126+99~ubuntu17.10.1 amd64 base library for VLC and its modules 

但我现在甚至无法删除它，

并且，我无法运行--fix-broken install因为它会尝试执行失败的相同操作…

Answer 1

我有同样的问题。 请尝试以下步骤：

 sudo dpkg --purge libvlccore8 sudo apt-get --fix-broken install sudo apt-get update sudo apt-get -y upgrade 

Answer 2

为了解决这些问题，我跑了

 rm -rf /usr/lib/x86_64-linux-gnu/libvlccore.so.9.0.0 apt-get --purge --yes remove '*vlc*' 

这种沉重的方法最终消除了VLC的所有痕迹。 从那时起，我想我可以重新添加它。 但随后，可能出现了真正的问题。 PPA中的内部版本字符串是borked 。

为了使您的系统进入合作状态，您必须手动删除libvlccore.so.9.0.0 ，否则dpkg无法继续。
