I downloaded Salome_meca 2025 for windows and installed it on Windows 11 and it works ok so far.
But then I switched to other laptop with Ubuntu 24.04. I downloaded the .sif file from here to a /home/jcsaaver/containers folder.
Then I installed singularity with:

sudo apt install singularity-container

And after that I did:

singularity run --app install salome_meca-lgpl-2025.1.0-1-20251026-scibian-12.sif

Then I run

/home/jcsaaver/containers/salome_meca-lgpl-2025.1.0-1-20251026-scibian-12

And the program starts normally.
But then I click on shaper module and it closes.

Here is what appears on the terminal:

jcsaaver@HP:~/containers$ /home/jcsaaver/containers/salome_meca-lgpl-2025.1.0-1-20251026-scibian-12

In case it helps, these are my system characteristics:
