when i try to start gufw i have such error
/usr/bin/gufw-pkexec: line 15: 8787 Segmentation fault (core dumped) python ${LOCATIONS[${i}]} $1

python-gobject installed

I've tried to reinstall both, gufw, python-gobject, restarted ufw to default, no success

ufw itself is working, state active

Same issue on Arch Linux (Antergos actually). See bug report there: https://bugs.archlinux.org/task/52599

Status changed to 'Confirmed' because the bug affects multiple users.

On Ubuntu 17.10 Beta 2 I get

Hi,
Could you run this command?

$ whereis python3

Thanks in advance!

Type the following command in a terminal:

echo $XDG_SESSION_TYPE

If it returns Wayland, type:

xhost si:localuser:root

to allow root to start graphical apps under Wayland sessions.
