Hi @hyjun0407

Try using the latest version of GEF from main and use the correct syntax from the docs.

Hi guys, I'm facing this same problem on ubuntu, and I don't understand why. I used kali linux and it was possible to see the stack view, but for some reason in ubuntu it is not possible to do this.

Marked as stale as this needs more info. I cannot reproduce, if anyone can, update this issue with a full step by step.
