因此，我尝试使用 [本指南][1] 在 Ubuntu 18.04 上安装 RetroPie，但运行后./retropie_setup.sh，出现以下错误sudo apt uprade：
$ sudo apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libsdl2-2.0-0 : Breaks: libsdl2-2.0-0:i386 (!= 2.0.8+1) but 2.0.8+dfsg1-1ubuntu1.18.04.1 is installed
libsdl2-2.0-0:i386 : Breaks: libsdl2-2.0-0 (!= 2.0.8+dfsg1-1ubuntu1.18.04.1) but 2.0.8+1 is installed
libsdl2-dev : Depends: libsdl2-2.0-0 (= 2.0.8+dfsg1-1ubuntu1.18.04.1) but 2.0.8+1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
我sudo apt --fix-broken install尝试修复此问题但收到更多错误：
$ sudo apt --fix-broken install

我该如何修复此问题？
答案1
我跟着这些说明然后跑了
sudo mv /usr/share/doc/libsdl2-2.0-0/copyright /usr/share/doc/libsdl2-2.0-0/copyright.backup
sudo apt --fix-broken install` and that seems to work.
现在我收到的唯一信息是
W: APT had planned for dpkg to do more than it reported back (150 vs 154).
Affected packages: libsdl2-dev:amd64
