我对 ubuntu 还比较陌生，在安装 retroarch 以及任何需要安装 libsdl2-2.0-0 的东西时遇到了问题，我尝试了多种安装方法，但似乎都不起作用，这里是一些最常用方法的主要日志。

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libsdl2-dev : Depends: libsdl2-2.0-0 (= 2.0.4+dfsg1-2ubuntu2) but it is not installed
E: Unmet dependencies. Try using -f.
