No protocol specified Unable to init server: Could not connect: Connection refused

(nautilus:5657): Gtk-WARNING **: cannot open display: :0

I tried the solution mentioned in a similar question on askFedora about killing all Nautilus related processes. It didn't work

Are you trying to start Nautilus with sudo privileges? That does not work under Wayland, see here.

Please also see Comment 4 here:

As said, it is that under Wayland, X11 clients run as another user (via su or sudo) are not authorised to connect to the X11 display server.

The bug relates to GParted, but you can try running proposed solution n°2, it works for Nautilus as well.

Thanks!!! I typed "xhost +local:" as mentioned, in the terminal and it worked!

The more permanent and correct solution to your problem (running nautilus as su or sudo in order to modify root-owned files) is the implementation of a protocol (called admin://) that let's you access root-owned files. Then, Nautilus UI is run as regular user, and the protocol requests the needed permissions using PolKit

Looks like this update will reach users with nautilus 3.24 ... in the meantime and until many other application get re-written, use work-arounds, or just XServer and not wayland

Are you able to launch it normally via desktop launcher? I assume not since you've tried opening it from the terminal.

Anyhow can you try reinstalling nautilus to see if that will help in resolving the issue?

sudo dnf reinstall nautilus
