The "crash" of gufw can easily be explained and fixed. However, I am not
sure we actually want this.
This is verified in bullseye: gufw 20.04.1-1
/usr/bin/gufw tests if we are under wayland and calls xhost:
if [ $(loginctl show-session $(loginctl|grep $(whoami) |awk '{print
$1}') -p Type) = "Type=wayland" ]; then
xhost +si:localuser:root
fi
which is in package "x11-xserver-utils" but which is not recorded by any
Debian package dependency.
So under wayland, "x11-xserver-utils" needs to become a dependency of
package gufw, or we crash as root cannot display stuff on the screen.
The question is whether we actually want such a far-reaching xhost
command sneaked in.
