Thanks for filing this bug in Ubuntu. This is possibly the error: Setting up apache2 (2.4.7-1ubuntu4.16) ... ERROR: Module mpm_event is enabled - cannot proceed due to conflicts. It needs to be disabled first! dpkg: error processing package apache2 (--configure): subprocess installed post-installation script returned error exit status 1
That error message is printed when a2enmod is called to enable another mpm module without disabling the current one first. For example: ubuntu@trusty-apache:~$ sudo a2query -M event ubuntu@trusty-apache:~$ sudo a2enmod mpm_prefork Considering conflict mpm_event for mpm_prefork: ERROR: Module mpm_event is enabled - cannot proceed due to conflicts. It needs to be disabled first! Considering conflict mpm_worker for mpm_prefork: Somehow you got yourself into that situation during package installation. Could you please provide the following: - output of "sudo a2query -M" - output of "sudo /usr/sbin/apachectl -D DUMP_MODULES" (might fail, as it did fail when apport opened this bug) - ls -la /etc/apache2/mods-enabled/ - dpkg -l|grep apache Thanks ** Changed in: apache2 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1707375 Title: package apache2 2.4.7-1ubuntu4.16 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/apache2/+bug/1707375/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
