5. Gufw won't start - been like this for months

  • Gufw won't start - been like this for months

    Lenovo Thinkpad X260 i7
    When running gufw from gnome gui it asks for password and nothing happens.
    When ran via terminal this is the output:

    Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused
Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused

    A word on fix would be welcome.

  • Anyone? Firewall Configuration (gufw) won’t start.

  • Hi @gozo ,

    I cannot reproduce it here. How did you install gufw? Are you running it with your user?

    It’s obvious it’s crashing, but I don’t know why.

    Have you tried to remove it and reinstall it?

    sudo pacman -Rnsc gufw
sudo pacman -S gufw

    Did you install it using pip or pip2? Then you should remove it and reinstall it with pacman.

    Check that you have this file:
    /usr/lib/python3.6/site-packages/gufw/gufw.py

    I don’t have more ideas… sorry.

  • HI @karasu,

    I did not install Gufw myself, it came with Antergos under name Firewall Configuration.
    I not, as per your instructions, uninstalled it and installed again, 3.7 megs install, all completed flawlessly.

    However, still, when I click icon Firewall Configuration or try running gufw from terminal, it asks for root password and does nothing. In other words - breaks. This is a native machine, not virtual.

    Anyone?

    Thanks.

    /usr/bin/gufw-pkexec: line 13:  1718 Segmentation fault

    Line 13 is the end of the skript… so may it is caused by a dependency?
    I would try what karasu say uninstall it with

    pacman -Rsn gufw

    and remove the rest:

    rm -R /etc/gufw
rm -R /root/.cache/gufw.py

    then reboot and reinstall

  • I tried, ARC and Numix Frost - not working.

    Interesting thing is - when I try from a virtual machine, using VirtualBox, Antergos Mate has the same issue.

  • Still having the same issue.

  • Hi,

    Interesting thing is - when I try from a virtual machine, using VirtualBox, Antergos Mate has the same issue.

    Then I’ll try this in a clean system in order to reproduce it. Did you install gufw using the installer?

  • i will try now in virtual with gnome…

  • Maybe you can find some helpful info here? : https://bugs.archlinux.org/task/52599

  • Thank you Dazzled. It’s good to know gufw team knows about it, and someone is working on it.

  • reading thru the bug report they come up with this typical wayland problem on “root apps can not start”

    @gozo plz type this in a terminal:

    echo $XDG_SESSION_TYPE

    if it shows wayland you need to do that:

    xhost si:localuser:root

    to allow root to start graphical-app under wayland session owned by your user…

    Source: gparted
    gparted wants to run as root. Before starting it, allow root user to display applications on your desktop by typing the following in a command line
