Public bug reported:

I'm encountering this systemd service dependecy cycle, which prevent
cloud-init from running, and making my image build unusable since user-
data settings do not get applied.

Issues present on bionic and focal


Steps to reproduce:

1. apt-get purge -y ufw; apt-get install -y firewalld
2. cloud-init clean
3. reboot
4. grep -B 5 cycle /var/log/syslog


I've seen these two error messages:
