I'm a Gufw developer.

You can not run any root UI (Gparted, Synaptic, Gufw...) because of Wayland.

Related bug: https://bugs.launchpad.net/ubuntu/+source/gui-ufw/+bug/1713238

All info here: https://bugs.launchpad.net/ubuntu/+source/backintime/+bug/1713313/comments/44

As you can read in that link, I'm afraid that it will be not fixed, because it was closed as won't fix :/

https://bugzilla.redhat.com/show_bug.cgi?id=1274451

A hug and I'm so sorry.

A dirty workaround, but this is one way to make gufw work on Ubuntu 17.10 with Wayland:

  • Create the file ~/bin/gufw and give it this contents:

    #!/bin/sh
xhost SI:localuser:root
/usr/bin/gufw
xhost -SI:localuser:root

  • Make the file executable:

    chmod +x ~/bin/gufw

Edit:

A more step by step explanation would be:

  • Press Ctrl+Alt+T to open a terminal window.

  • Run the command:

    mkdir -p bin

    (i.e. type it and press Enter)

  • Open the gedit text editor with this command:

    gedit bin/gufw

  • Copy the contents as above and paste it into the gedit window.

  • Save and quit gedit.

  • Run the command:

    chmod +x bin/gufw

  • Quit the terminal window by running the command:

    exit

Re-installation not really required;

After a quick search, I found that Gufw is missing a python dependency. It appears that the python-gi package needs to be added as a dependency.

Steps to fix:

  1. sudo apt install python-gi
  2. gufw
  3. Type in password

I had the same issue. Accidentally found the solution for gparted over SSH here.

sudo -E gufw

This should work - assuming /etc/ssh/sshd_config is properly configured.

xhost si:localuser:root

pip3 install ufw
sudo apt-get install python-gobject
sudo apt-get install --reinstall gufw
sudo gufw

worked for me on Ubuntu 18.04! I had the same issue! I hope I'm not forgetting any cmd as I tried a lot of things...
