    On CentOS 7.4, since I have installed fail2ban using "yum", rpm fails to find fail2ban's package and therefore I solved it this way:

    yum install fail2ban-all.noarch

    But I'm sure it's possible to narrow down "-all.noarch" to something more minimalistic.

    Thank you for sharing.

    Provided solution is applicable only for 'fail2ban' package shipped with Plesk. It does not cover similar issues for fail2ban provided by other 3rd party repositories or OS vendor.
