Missing libGL on Fedora, cannot install it

Question

Problem

After a recent system update (on Fedora 25) I have some problems with my graphics card (GeForce 1060, using the proprietary driver from RPM Fusion), so I wanted to get diagnostics information using glxinfo.

However, glxinfo can't find libGL:

glxinfo: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

What I've tried

Using DNF, I found out that mesa-libGL contains the missing file:

$ dnf repoquery -l mesa-libGL

/usr/lib/libGL.so.1
/usr/lib/libGL.so.1.2.0
/usr/lib/libGLX_mesa.so.0
/usr/lib/libGLX_mesa.so.0.0.0
/usr/lib64/libGL.so.1
/usr/lib64/libGL.so.1.2.0
/usr/lib64/libGLX_mesa.so.0
/usr/lib64/libGLX_mesa.so.0.0.0

This package was already installed but no libGL.so.* exists anywhere on the system and reinstalling the package with dnf reinstall didn't help either (find / -name libGL.so.* doesn't output anything).

Question

Why isn't libGL.so.* installed? Could it have something to do with the Nvidia driver?

Answer 1

I found out what the problem was. dnf repoquery -l mesa-libGL outputs the files of all package versions. In this case, libGL.so.1 is only included in mesa-libGL-12.0.3-3.fc25.i686, which is not the version I have installed. Apparently, the package authors changed some dependencies and libGL.so.1 is now part of libglvnd-glx:

$ dnf repoquery -l libglvnd-glx.x86_64

/usr/lib64/libGL.so.1
/usr/lib64/libGL.so.1.0.0
/usr/lib64/libGLX.so.0
/usr/lib64/libGLX.so.0.0.0

After reinstalling the package, glxinfo works again.
