We also had it updated and fail2ban worked perfectly except it did not ban anymore on the sshd jail. This was caused by the /etc/fail2ban/filter.d/sshd.conf file which should have been replaced with a new one from the rpm (there was a sshd.conf.rpmnew file). Below the error we found in /var/log/fail2ban.log : 2019-12-09 10:02:15,294 fail2ban.filtersystemd [13628]: INFO [sshd] Added journal match for: '_SYSTEMD_UNIT=sshd.service + _COMM=sshd' 2019-12-09 10:02:15,295 fail2ban.filter [13628]: ERROR No failure-id group in 'normal' 2019-12-09 10:02:15,295 fail2ban.transmitter [13628]: WARNING Command ['set', 'sshd', 'addfailregex', 'normal'] has failed.
