我试图从 texlive 2015 更新到 2017。
我运行了以下命令：
sudo add-apt-repository ppa:jonathonf/texlive-2017
sudo apt-get update
sudo apt-get install texlive-full
运行最后一行后，我得到了很多具有未满足依赖项的包名称和以下错误：
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
但是运行会
sudo apt-get -f install导致另一个错误
