Productive Workstation with Linux 06 - Installing NNN, cd-on-quit and adding file preview

I get this: "Error: dial unix /tmp/nnn.fifo: connect: connection refused", any idea why ? I did the exact same thing he did in the video

Hi there, what Distro are you using? I been trying to compile nnn with a test ubuntu 18,22,23 and all of them give me errors.
