Warning: Geometry Viewer not found

I have installed fluka flair and geoviewer following Fluka for Docker | Running Fluka on Windows (macOS, Linux) machines using Docker (flukadocker.github.io) and FLUKA on Windows 10/ 11 using WSL | Fluka for WSL (flukadocker.github.io) links in docker and local host respectively.

But after executing ‘‘flair’’ command it showed Warning: Geometry Viewer not found
Error: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38’ not found (required by /usr/local/flair/geoviewer.so) from both the installs.

Thanks in advance
