我在使用更新管理器时遇到问题。正常安装时出现以下情况：
~$ sudo apt-get install
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
ffmpeg : Depends: libvdpau1 (>= 0.2) but it is not installed
mesa-vdpau-drivers : Depends: libvdpau1 but it is not installed
vdpau-va-driver : Depends: libvdpau1 (>= 0.2) but it is not installed
E: Unmet dependencies. Try using -f.
使用推荐的选项：
~$ sudo apt-get -f install

有人知道问题可能是什么吗？我尝试了这里所有类似问题的解决方案，但都没有用。
答案1
-删除 vdpau_wrapper.cfg 文件并强制安装
sudo rm -rf /etc/vdpau_wrapper.cfg
sudo apt-get install -f
答案2
以下对我有用：
sudo apt-get remove libvdpau1
sudo apt-get -y install libvdpau1
然后我安装了被阻止的软件包。
