[Ben Hockley (oohbuntu)]

The underlying problem seems to be that the package installer assumes the existence of the (recently deprecated?) /etc/apache2/conf.d/ directory - so installation likely to be broken on fresh installations or upgrades from recent versions.

From googling, it looks like /etc/apache2/conf.d/ was replaced by /etc/apache2/conf-available/ in apache 2.4 - so it is the change to apache that has broken this package, I guess?

Status changed to 'Confirmed' because the bug affects multiple users.

[Ben Coleman (b-coleman)]

This problem still exists in 14.04.

Super annoying issue on 14.04, makes the package unusable.
