Hello,

I am having issues with installing Ansys on an Ubuntu computer that was upgraded from 18.04 to 20.04 LTS. I am receiving this error message when I execute runwb2:

An unexpected error has occurred: Could not find a part of the path "/home/user/.config/Ansys/v222/UnitSystems/Ans.Units.config".
System.IO.DirectoryNotFoundException: Could not find a part of the path "/home/user/.config/Ansys/v222/UnitSystems/Ans.Units.config".

I also have downloaded all libraries in the Ansys Installation Guide for Ubuntu, but I am still receiving the error message above, and also the .config/Ansys/v222 directory is empty in my case.

I was able to get it working by copying the ~/.config/Ansys/ folder from another computer of mine to the computer that has the issue, and it seems to be working just fine. Although, I hope there is a better solution for this.
