The guide recommends the Gufw firewall GUI.
I installed it by apt
gufw/oldstable,oldstable,now 12.10.0-1 all [installed]
graphical user interface for ufw
Typing ẁindow key + gufw, I cannot see the application.
Only access is through terminal by gufw which is not enough.
I am thinking why so + how to fix the issue because I am systematically using too little firewall in Linux.

aptshows me two packages existing forgufw. Typinggufwin terminal opens the older version 12.10. What do you think?apt-cache policy gufwand perhaps for completenessdpkg -l gufw?apt -t unstable install gufw?unstableversions, at your peril) or see if it can somehow be made to work with dependencies ignored. (You probably have older versions of these packages; if you are lucky, they could just happen to work.)
