My system is a Lenovo Thinkpad T450s with integrated graphics. After an upgrade from Lubuntu 18.04 to 18.10 (I only learned after this upgrade that you're not supposed to do it), I'm having trouble running a GameMaker game in Wine, presumably due to a lack of a 32-bit libGL:
0009:err:wgl:init_opengl Failed to load libGL: libGL.so.1: cannot open shared object file: No such file or directory
I think libglx-mesa0:i386 might be the right package to install, but I'm getting some strange errors when trying to install it, which suggest screwed-up dependencies. I previously had some Intel drivers installed from a PPA, but I ppa-purged it before the upgrade. What should I do now?
$ sudo apt install libglx-mesa0:i386

Fkraiem's suggestion in the comments—to re-add the PPA, update, upgrade, and finally
ppa-purgeit again—resolved the dependency issue. I was able to installlibglx-mesa0:i386. That turned out not to providelibGL.so, butlibglvnd-dev:i386did.
