包libvlccore9中的vlc-masterPPA 正在尝试安装，/usr/lib/x86_64-linux-gnu/libvlccore.so.9.0.0该安装应该由 进行安装libvlccore8。

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
而且，我无法运行，--fix-broken install因为它尝试做同样的事情，但失败了......

答案1
我也遇到了同样的问题。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
答案2
为了解决这些问题我运行
rm -rf /usr/lib/x86_64-linux-gnu/libvlccore.so.9.0.0
apt-get --purge --yes remove '*vlc*'
这种粗暴的做法最终删除了 VLC 的所有痕迹。从那时起，我想我可以重新添加它。但随后，真正的问题可能就出现了。PPA 中的内部版本字符串被破坏。
为了使您的系统进入一致状态，您必须手动删除libvlccore.so.9.0.0，否则 dpkg 无法继续。
