Package: fail2ban Version: 0.11.2-2 Severity: important When I try to install fail2ban (as a dependency of a metapackage) into a Debian bullseye Docker container, the fail2ban postinst errors with the message "Have not found any log file for sshd jail", causing the dpkg process ran by apt to fail. A similar message occurs in buster, but the message does not result in an error and apt install failure.
