I'm having a similar issue. I'm unable to install Ansys EM Desktop.
My machine is running Ubuntu 20.04.6. I've installed all the library dependencies mentioned by Ansys_Mmadore.
But the installation is failing with:
/home/aditya/Downloads/Electronics_231_linx64/Linux/install.exe: symbol lookup error: /usr/lib/x86_64-linux-gnu/libXrender.so.1: undefined symbol: _XGetRequest
This problem is replicated on two independent machines running Ubuntu 20.04.
Any help would be greatly appreciated!
