A Surprise stop to the firewall ...kali linux 2.0

[engwla2]

I did some quick searching and could not find any current solutions to a problem
like this in forums linux Kali specifically.
When you run a firewall in kali linux 2.0 after two minutes or less stops working
and gives an error message
If you allow me this video clip Explain the problem

I sow it. Try this simple steps.
1.)remove gufw
2.)clean system with Bleachbit (don't use in System: Free disk space;Localisation;Memory)
3.)update & upgrade
4.)install ufw (not gufw)

see what happens
Nice and clean post about ufw
