当我尝试安装时，libsdl2-dev出现以下信息：
The following packages have unmet dependencies.
libsdl2-dev : Depends: libegl1-mesa-dev but it is not going to be installed
Depends: libgl1-mesa-dev but it is not going to be installed
Depends: libgles2-mesa-dev but it is not going to be installed
Depends: libglu1-mesa-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我从 xenial 升级了全新安装，并遇到了这些问题。
我按照惯例进行了apt-get dist-upgrade清理，但没有成功。当我开始添加提到的其他软件包时，似乎陷入了无休止地添加要安装的额外软件包的困境。
下面是根据要求的输出
cd /etc/apt&&find -name \*list -exec egrep -vH "^#|^$" {} \;
，我必须通过http://从输出中删除来进行修改，因为不允许超过 2 个链接。

答案1
首先清理并更新你的存储库：
$ apt-get clean
$ sudo dpkg --configure -a
$ sudo apt-get -f install
$ sudo apt-get update
然后彻底删除问题应用程序。
$ sudo apt remove --purge libsdl2-dev
清除应用程序后，请正常重新安装。如果失败，请执行更强力的删除：
$ sudo dpkg --remove --force-remove-reinstreq libsdl2-dev
完成后应充分清除冲突并允许其正确安装。
