libGL.so.1: cannot open shared object file

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


You can use strace to debug the program you're trying to execute - this should show you exactly which directory paths it's looking in for libGL.so.1. Then you can run find /usr -name libGL.so* or an apt-file search. Typically though, you can just install or reinstall the appropriate glx package - for example:


# apt-get install --reinstall libgl1-mesa-glx
