package w3c-markup-validator 1.3+dfsg-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

vim /var/lib/dpkg/info/w3c-markup-validator.postinst

Commenting out this blocked allowed me to prevent having a broken package:
# if [ ! -s /etc/$server/conf.d/w3c-markup-validator.conf ]; then
# ln -s /etc/w3c/httpd.conf \
# /etc/$server/conf.d/w3c-markup-validator.conf
# fi

The reason this isn't working is because there's no conf.d directory in the /etc/apache2 directory:
ls /etc/apache2/
apache2.conf conf-available conf-enabled envvars magic mods-available mods-enabled ports.conf sites-available sites-enabled

I assume this should point to /etc/$server/conf-available instead:
   ln -s /etc/w3c/httpd.conf \
                    /etc/$server/conf-available/w3c-markup-validator.conf
