最近安装了 20.04 并启用了 FIPS，然后尝试安装一个名为 ffmpeg 的软件包，但失败了。
我尝试在装有 20.04 的笔记本电脑上安装同一个软件包，没有出现任何问题。
有没有人遇到过下面显示的此类问题：
sudo apt install ffmpeg

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
ffmpeg : Depends: libavdevice58 (= 7:4.2.4-1ubuntu0.1) but it is not going to be installed
Depends: libavresample4 (= 7:4.2.4-1ubuntu0.1) but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
