This has been reported on the ansible module side as well as it impacts the ability to configure ufw on Ubuntu 20.04.02 LTS servers. ufw is essentially unusable because of this bug.

Perhaps you want to use the -w option? ``` it seems that in utils.py, get_netfilter_capabilities(...) iptables is called without "-w" flag to wait for the table lock perhaps the checks should include this parameter to avoid leaving temporary tables behind (and breaking fail2ban, but thats a different story ...)?
