Resolved fail2ban cannot be started

[TorbHo]

After migration of a lot of domains from backup, fail2ban cannot be started.

Plesk Onyx
17.5.3 Update #13
‪Ubuntu 16.04.2 LTS‬

Error message:

Fehler: Die Einstellungen können nicht gespeichert werden: f2bmng failed: Synchronizing state of fail2ban.service with SysV init with /lib/systemd/systemd-sysv-install...
Executing /lib/systemd/systemd-sysv-install enable fail2ban
Job for fail2ban.service failed because the control process exited with error code. See "systemctl status fail2ban.service" and "journalctl -xe" for details.

systemctl status fail2ban.service shows:

Now it works.

I uninstalled the fail2ban extension AND removed the /etc/fail2ban directory via ssh.
After that, I reinstalled the extension via:

# /usr/local/psa/admin/sbin/autoinstaller --select-release-current --install-component fail2ban​
