Hashcat not outputting to output file or terminal

basically I installed Ubuntu (ver 18.04) and followed this guide for installing hashcat https://www.alexanderjsingleton.com/infosexy-how-to-use-hashcat-to-crack-passwords-in-ubuntu-18-04/ , except for the SSH and intel openCL parts.
The problem I’m facing is that when i run hashcat using the command in the guide it doesn’t output to a file or show the results in terminal. I’ve tried looking for a solution but nothing worked (I’ve tried adding “–show”, " --potfile-disable" and “–potfile-path”, none work and it doesn’t out output to the potfile).
Does anyone know what the problem is or can help me solve it?

Thank you.

can you post the command you are using?

have you tired with root?
