Folks, Not worth raising a full bug report, I think: On page https://www.debian.org/international/Turkish.en.html - Also, we suggest you to visit the site Debian-tr <http://www.debian-tr.org> where you can find more detailed Turkish documentation.
It looks to me as if the Debian-tr site referenced has not been renewed / lost to domain squatting. I'm guessing that the translations will also have to be updated. All the very best, Andy Cater
