Here is a clarification of what is happening : /usr/sbin/a2query has indeed a bug that will generate this error :
usage: fail($reason, $retval) at /usr/sbin/a2query line 168. This is fixed by https://anonscm.debian.org/cgit/pkg- apache/apache2.git/patch/debian/a2query.in?id=0e26141c6b013a9c889f02f1e2077834d38228f0 that adds the $retval return value in a few places : @@ -203,7 +203,7 @@ sub load_defaults sub load_modules { my $conf_dir = $CONFIG_DIR .

Do not proceed due to undefined results" that is causing a2query to fail. If a2query was to be fixed, the /var/lib/dpkg/info/libapache2-mpm- itk.postinst would still fail with the following error : /var/lib/dpkg/info/libapache2-mpm-itk.postinst: 9: [: !=: unexpected operator since a2query sends the fail() error message to stderr. In all cases, this situation is caused by a problem with the apache2 configuration (either two MPM being configured which should not happen or problem with /etc/apache2/mods-enabled) and not with the apache2-mpm- itk package being SRUed. I am marking this bug as Invalid as this is not a regression caused by the apache2-mpm-itk SRU. ...Louis ** Changed in: mpm-itk (Ubuntu) Status: Incomplete => Invalid ** Tags added: bot-stop-nagging -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1590283 Title: package libapache2-mpm-itk 2.4.6-01-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mpm-itk/+bug/1590283/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
