Failed during configuration: Have not found any log file for sshd jail #3567

From other point of view it is a configuration issue and can be surely simply fixed using:

- echo -e "[sshd]\nenabled=true" | sudo tee /etc/fail2ban/jail.local
+ echo -e "[sshd]\nbackend=systemd\nenabled=true" | sudo tee /etc/fail2ban/jail.local

With other words:

  $ sudo cat /etc/fail2ban/jail.local 
  [sshd]
+ backend=systemd
  enabled = true
