Bug#734865: libapache2-mpm-itk: fails to install: subprocess installed post-installation script returned error exit status 1
It's currently not possible to reinstall (or, when a new release comes along, upgrade to a newer version) because postinst is doing, as Eric pointed out, (essentially) an a2enmod mpm_itk--and this call fails if mpm_itk is already enabled. The problem belongs to apache2, however: /etc/apache2/mods-available/mpm_prefork.load declares: # Conflicts: mpm_event mpm_worker mpm_itk but mpm_itk.load (as of the latest version) depends on mpm_prefork: # Depends: mpm_prefork a2enmod considers the dependency satisfied the very first time an 'a2enmod mpm_itk' happens, because, at that time, mpm_itk isn't active yet, so the mpm_prefork dependency is satisfied. If mpm_itk is already enabled, `a2enmod mpm_itk' fails because its mpm_prefork dependency now fails because the mpm_prefork dependency can't be enabled: # a2enmod mpm_itk 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.Considering dependency mpm_prefork for mpm_itk: Considering conflict mpm_event for mpm_prefork: Considering conflict mpm_worker for mpm_prefork: Considering conflict mpm_itk for mpm_prefork: ERROR: Module mpm_itk is enabled - cannot proceed due to conflicts. It needs to be disabled first! ERROR: Could not enable dependency mpm_prefork for mpm_itk, aborting Long story short: apache2 needs to remove the conflict with mpm_itk from mpm_prefork.load. -- Jason Rhinelander -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Jason Rhinelander debugged this earlier today; it seems like mpm_prefork declares a conflict with mpm_itk. But I guess the issue of mpm_event is a separate one? I don't know how to set the severity for this correctly; it might be RC for mpm-itk (although I'm still not 100% convinced), but it's not RC for apache2. /* Steinar */ -- Homepage: http://www.sesse.net/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

The logfile has the piuparts command line used for the test at the top, you may have to adjust paths etc. My piuparts test machine is currently offline, so I cannot check in detail. I assume it is related to (one or more of) setting DEBIAN_FRONTEND=noninteractive, stdin being redirected from /dev/null and policy-rc.d forbidding to start services, and everything happening in a minimal chroot.

I think this is a separate issue; it was discussed when we split out mpm-itk as a separate package, and the general sentiment was that it will work for wheezy - jessie, but not necessarily sid - sid (the latter is not strictly supported).

Sid users will be warned, but the related postinst code is not supposed to fail in that case. Please check if your maintainer scripts work as expected, as the issue seems to be, that you enable the itk module, before disabling the current (default) mpm. See [1] for properly switchting MPMs in maintainer scripts. On a side note, Andreas would it be possible to do piuparts checks related to Apache and its modules with APACHE2_MAINTSCRIPT_DEBUG=true defined in the environment? That would make the logs more useful.
