If you're a Ubuntu 16.04 user and stumble across this like I did, then for Ubuntu 16.04; in disable-transparent-huge-pages.service simply replace instances of /usr/bin with /bin.

The quoting as displayed here does not work. I removed the quotes around "never" but perhaps escaping them would work too.
