I encountered this bug as well. The postinstall script ends up calling: a2enmod -m -q mpm_itk
which prints: WARNING: MPM_ITK is a third party module that is not part of the official Apache HTTPD. It has seen less testing than the official MPM modules. ERROR: Module mpm_event is enabled - cannot proceed due to conflicts. It needs to be disabled first! ERROR: Could not enable dependency mpm_prefork for mpm_itk, aborting by disabling mpm_event with # a2dismod mpm_event the installation appears to proceed normally. -eric -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
