It doesn't run properly when I click and closes automatically.
This post on reddit says that it's because of a broken dependency and the fix for that is:
sudo apt-get install python-gobject
After typing that in a terminal, I'm now able to start GUFW.
I have installed it today (
2016.05.06) and everything works fine.
I'm using GUFW version
16.04 with kernel
I already had the package
python-gi installed at version
Had this problem in Debian Stretch RC3. Basic setup. What fixed it was net-tools package.
sudo apt-get install net-tools
