O guia recomenda a GUI do firewall do Gufw.
Eu instalei por apt
gufw/oldstable,oldstable,now 12.10.0-1 all [installed]
graphical user interface for ufw
Digitando a tecla + gufw, não consigo ver o aplicativo.
Apenas o acesso é feito pelo terminal gufw , o que não é suficiente.
Eu estou pensando por que então + como corrigir o problema porque eu estou sistematicamente usando muito pouco firewall no Linux.

gufw/oldstable,oldstable,now 12.10.0-1 all [installed]
graphical user interface for ufw
Instalação pelo método apt install gufw
Saída de apt show -a gufw onde estou pensando em dois pacotes (17.04 e 12.10) para algo conflitante no meu sistema - por algum motivo gufw no terminal inicia gufw 12.10

O Debian Stretch foi lançado há algumas semanas. Atualizar todo o seu sistema para isso parece ser a solução mais fácil para o seu enigma.
O bug foi corrigido na versão do Debian Stretch, enquanto o antigo stable Jessie ainda estava preso em uma versão de quase cinco anos atrás.
