Idézem/Quoting Peter Chubb <peter.ch...@data61.csiro.au>:
Package: fail2ban Version: 0.10.2-1 Severity: normal Dear Maintainer, After upgrading fail2ban, it no longer starts. The error message is: fail2ban Failed during configuration: Bad value substitution: option 'mode' in section 'Definition' contains an interpolation key 'ddos' which is not a valid option name. Raw value: '%(ddos)s' The problem is in /etc/fail2ban/filter.d/sshd-ddos.conf
It seems to be that the sshd-ddos filter has been merged into sshd. Please see sshd.conf for details and remove sshd-ddos.conf and set [sshd] mode = ddos. I hope this helps you.
