尝试（重新）安装 ffmpeg，但未满足依赖关系

Question

我之前尝试按照https://ubuntuhandbook.org/index.php/2022/02/install-ffmpeg-5-0-ubuntu/在 ubuntu 20.04 LTS 上安装 ffmpeg 5，但没有成功。现在我已经升级到 Ubuntu 22.04.2 LTS（它也有自己的问题）。我仍然无法正确安装ffmpeg；

当我现在有版本 22 时，apt 试图安装版本 20 的依赖项，这是怎么回事？

Answer 1

按照建议的问题建议表https://askubuntu.com/a/60314/1030659 sudo aptitude install ffmpeg 让我选择未满足的依赖项并从 ubuntu20 版本“降级”到 ubuntu22 版本。我现在已经定期安装了 ffmpeg ffmpeg version 4.4.2-0ubuntu0.22.04.1 Copyright (c) 2000-2021 the FFmpeg developers

然而遗憾的是这仍然不是 ffmpeg 版本 5，但这确实解决了我的麻烦。
