When you come accorss this error after uninstalling Firehol. Check that you don't have this block:

[Unit]
# Starting fail2ban will automatically start firehol before it.
# Stopping firehol will automatically stop fail2ban before it.
BindsTo=firehol.service
After=firehol.service

in /etc/systemd/system/fail2ban.service.d/override.conf or systemctl edit fail2ban

If you have it, delete it and start/ restart fail2ban service. Sometimes, we need to reverse what we have done when we followed the documentation.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
