Comment 28 for bug 562370

I had this error for a while:

Setting up apache2.2-common (2.2.14-5ubuntu8.2) ...
ERROR: Module reqtimeout does not exist!
dpkg: error processing apache2.2-common (--configure):
 subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of apache2-suexec:
 apache2-suexec depends on apache2.2-common; however:
  Package apache2.2-common is not configured yet.
dpkg: error processing apache2-suexec (--configure):

dpkg: dependency problems prevent configuration of apache2-mpm-itk:

                           No apport report written because the error message indicates its a followup error from a previous failure.
                                                      Errors were encountered while processing:
 apache2.2-common
 apache2-suexec
 apache2-mpm-itk
E: Sub-process /usr/bin/dpkg returned an error code (1)

I solved it by running:

dpkg --purge --force-all apache2.2-common
 dpkg: apache2.2-common: dependency problems, but removing anyway as you requested:
 libapache2-mod-php5 depends on apache2.2-common; however:
 Package apache2.2-common is to be removed.
 libapache2-mod-perl2 depends on apache2.2-common.
 libapache2-mod-auth-mysql depends on apache2.2-common (>= 2.2.3-3).
 libapache2-mod-geoip depends on apache2.2-common.

Then reinstall it:
root@server:~# apt-get install apache2.2-common
