Graphicaluser interface of UFW firewall not start

#1 Post by coppolino97 »

Hi all,
I have installed ufw firewall on my laptop and I would manage it using the graphical user interface ( gufw).

This is the errors when I try to start it:

Code: Select all

Can't remember and not going to bother checking exactly what ufw's situation is on Debian gnu/nix but try "sudo systemctl status ufw", that doesn't pop anything up, try gufw etc. What's it saying is the deal with it ? Get any kind of result try enabling it and rebooting etc. "sudo systemctl enable ufw" and similar. Just random thoughts on this. Good luck. :)

How are you trying to start it? Which desktop environment (or window manager) is this? Do you have a graphical polkit authentication agent running?

I'm not sure if GUFW works under wayland. However you can use the XML interface by running:

Code: Select all

sudo ufw status verbose
or su to root and run:

Code: Select all

ufw status verbose
. You can write any rules you want easily from the ufw series of commands.
