Comment 2 for bug 1793190

Thanks for filing this bug in Ubuntu.

This is the error that was logged by dpkg:
ERROR: Module reqtimeout not properly enabled: /etc/apache2/mods-enabled/reqtimeout.load is a real file, not touching it^M
^[[1mdpkg:^[[0m errore nell'elaborare il pacchetto apache2 (--configure):^M
 installed apache2 package post-installation script subprocess returned error exit status 1^M

In the Ubuntu packaging layout, the mods-enabled directory should only contain symlinks to the ../mods-available directory. Which modules are enabled or not is controlled by the a2enmod/a2dismod pair of tools, which manage these symlinks.

It looks like in your case you have an actual file in mods-enabled instead of a symlink.

Could you please verify this:

ls -la /etc/apache2/mods-{available,enabled}/reqtimeout.load

If you get two files back, please compare them. If you made any changes to the one in the mods-enabled directory, please make these changes in the file from the mods-available directory instead, then remove the one from mods-enabled and use "sudo a2enmod reqtimeout" to properly enable it.
