fatal error on "firewall: Check if ufw package is installed (on Ubuntu)."

[agajic-modoolar]

Hello,

I decided to set firewall_disable_ufw flag to disable UFW, but repeating task causes fatal error. I was wondering, could service_facts module be used to determine if ufw exists, and to disable it if so? I'm Ansible beginner, but it seems a bit ugly to have fatal fails, even though they are ignored. Am I missing something here? I'm using Ansible 2.9.7
