w3c-markup-validator fails to create symlink during post-install

[Kevin Cozens]

I just installed Linux Mint 17.2 (64-bit) and I tried to install the w3c-markup-validator package (version 1.3+dfsg-1). The install failed at the post-install stage. The error message was:

ln: failed to create symbolic link ‘/etc/apache2/conf.d/w3c-markup-validator.conf’: No such file or directory

I have the 2.4.7-1ubuntu4.4 version of apache2 installed. The path should be:
/etc/apache2/conf-enabled/w3c-markup-validator.conf

Line 43 of w3c-markup-validator.postinst should be changed from
    /etc/$server/conf.d/w3c-markup-validator.conf
to
    /etc/$server/conf-enabled/w3c-markup-validator.conf
