I’ve recently re-installed paraview V5.7.0 on my Ubuntu machine (Ubuntu 20.04.3) using the apt-get install method.

When running paraview, the application opens fine, however the GLEW fails to initialise and i’m stuck unable to view any meshes in the window. I’ve tried uninstalling and reinstalling and restarting my machine, cleaning and updating my repository and a couple other things, but nothing seems to work.

Any help / ideas would be greatly appreciated…
