我需要 handbrake-cli 工具，但我认为它不包含在标准的 Ubuntu 存储库中，因此我遵循了这个指导。
添加存储库
sudo apt-get install ubuntu-restricted-extras
sudo apt-get install libdvdread4
sudo /usr/share/doc/libdvdread4/install-css.sh
sudo apt-get install python-software-properties
sudo apt-add-repository ppa:stebbins/handbrake-snapshots
sudo apt-get update
没有错误，一切似乎都很好。
安装过程中一切似乎都很顺利：
jdoe@jdoe:~$ sudo apt-get install -y handbrake-cli handbrake-gtk

还有一个问题
为什么默认 Ubuntu 存储库中的 handbrake 包中不包含 handbrake-cli？也许，这有一个很好的理由，我应该知道 :)
答案1
首先，您正在尝试使用适用于 Ubuntu 12.04 的方法当您使用 Ubuntu 14.04 时，这通常不起作用。
其次要注意的是，在 Ubuntu 12.04 中，命令是命名的ghb，而不是handbrake。
第三个handrake-cli已经在宇宙的默认 PPA 中建立。
现在要在 Ubuntu 14.04 中正确安装 Handbrake，只需运行以下命令：
sudo apt-get install handbrake handbrake-cli
但在此之前，请删除ppa:stebbins/handbrake-snapshots存储库。
sudo apt-get install ppa-purge
sudo ppa-purge ppa:stebbins/handbrake-snapshots
更新：
如果你想使用 stebbins repo：
sudo add-apt-repository ppa:stebbins/handbrake-releases
sudo apt-get update
sudo apt-get install handbrake handbrake-cli
