我的系统是联想 Thinkpad T450s，带集成显卡。从 Lubuntu 18.04 升级到 18.10 后（我直到这次升级后才知道不应该这样做），我在 Wine 中运行 GameMaker 游戏时遇到了麻烦，大概是因为缺少 32 位 libGL：
0009：err：wgl：init_opengl 无法加载 libGL：libGL.so.1：无法打开共享对象文件：没有此文件或目录
我认为libglx-mesa0:i386这可能是正确的安装包，但我在尝试安装时遇到了一些奇怪的错误，这表明依赖关系有问题。我之前从 PPA 安装了一些英特尔驱动程序，但我ppa-purge在升级之前就安装了。我现在该怎么办？

Fkraiem 在评论中提出的建议 — 重新添加 PPA、更新、升级，最后再来ppa-purge一遍 — 解决了依赖问题。我能够安装libglx-mesa0:i386。结果发现并没有提供libGL.so，但libglvnd-dev:i386确实提供了。
