[SOLVED] I got error for gufw on Hyprland

I'm a beginner in the Linux world. I'm learning slowly and I've encountered my first problem. I'm using ArchLinux with Hyprland. I've installed

ufw gufw

. When I try to run gufw, I get the following error. I've tried everything I've found and it's not worth it.

Re: [SOLVED] I got error for gufw on Hyprland

The package ships a polkit authorisation file so try

pkexec gufw

Re: [SOLVED] I got error for gufw on Hyprland

you need to launch a polkit agent: https://wiki.archlinux.org/title/Polkit … ion_agents -- doesn't really matter which one but pick one and start it as part of your startup programs

Re: [SOLVED] I got error for gufw on Hyprland

I think pkttyagent would have asked for a password if the OP ran my command from a terminal.

@OP: is the plain polkit package installed?

Re: [SOLVED] I got error for gufw on Hyprland

I don't know if the same is true with Hyprland but with Labwc/Xfce4 the user could not get privileges  to apps like gufw. Wayland doesn't allow it by default. For it to work I had to add a couple lines to the labwc autostart file. I assume hyprland has something similar. You will still have to call it from a terminal but it works.

 #### allow root/graphical use ####
xhost +SI:localuser:$(id -un) &
xhost +SI:localuser:root &

Good catch!

Probably best to use a wrapper with gufw though to reset the permissions after running it, something like this at /usr/local/bin/gufw should work:

#!/bin/sh
xhost +SI:localuser:root
pkexec /usr/bin/gufw "$@"
xhost -SI:localuser:root

Re: [SOLVED] I got error for gufw on Hyprland

Yes that would/should work just fine except that it's specific to gufw. You would need to do the same if there is any other graphical application requiring elevated privileges.

Re: [SOLVED] I got error for gufw on Hyprland

I suppose you could use pkexec itself and drop /usr/bin/gufw to make it universal.

Re: [SOLVED] I got error for gufw on Hyprland

Applications that want to do this should properly implement polkit auth so they can run their GUI code separate from the actual auth needing operation, which is adjusting ip/nftables...

It works for me with this.

If you can give me a simpler explanation.

Re: [SOLVED] I got error for gufw on Hyprland

There's nothing you can do about it as a user, so use the xhost method. The developers of gufw should implement proper privilege separation so that the GUI code doesn't need to be ran as root, but just the parts that require actual adjustment.
