当我运行 steam 时，它报告以下错误：
Running Steam on ubuntu 18.04 64-bit
STEAM_RUNTIME is enabled automatically
Pins up-to-date!
Error: You are missing the following 32-bit libraries, and Steam may not run:
libXtst.so.6
libXrandr.so.2
libXrender.so.1
libgobject-2.0.so.0
libgio-2.0.so.0
libgtk-x11-2.0.so.0

libgdk_pixbuf-2.0.so.0
libva.so.2
libvdpau.so.1
libva.so.2
libva-x11.so.2
Steam client's requirements are satisfied
我确信所有这些包都已正确安装。例如：
$ find /usr/ -name libXtst.so.6
/usr/lib/x86_64-linux-gnu/libXtst.so.6
/usr/lib/i386-linux-gnu/libXtst.so.6
有什么办法可以解决这个问题吗？
