Comment 3 for bug 1911637

Thanks for the report. I read the ansible bug but this issue is actually coming from the underlying iptables tool. Something on the system is manipulating the firewall via iptables at the same time that the ufw command is being run. As described, this would happen with any firewall software. If only ufw is being used with ansible, perhaps ensure that the ufw commands are not being run in parallel. The upstream bug referenced docker, which will also manipulate the firewall with iptables; perhaps ensure that ufw configuration is applied before docker is started.

I'm going to mark this bug as Invalid for now. Feel free to provide more information if you feel this is specific to ufw.
