Hi Holger, thanks for your attention to the bug report, but my report was about a different issue. Let me explain.
First, let's take a look at developers-reference as it pubished on the Debian's website. Say, in English [web-en]. It incorrectly links to translations as index.{fr,de,it,ru,jp}.en.html, such files do not exist. Any other translation, say, French [web-fr] links to translations as index.{de,it,ru,jp}.fr.html, such files do not exist. [web-en] https://www.debian.org/doc/manuals/developers-reference/index.en.html [web-fr] https://www.debian.org/doc/manuals/developers-reference/index.fr.html Second, let's take a look at developers-reference package. All links there are correct, that is in _any_ language links point to index.{fr,de,it,ru,jp}.html. Third, let's take a look at developers-reference source code. In English we currently have as follows: <para> If you want to print this reference, you should use the <ulink url="developers-reference.pdf">pdf version</ulink>. This page is also available in <ulink url="index.fr.html">French</ulink>, <ulink url="index.de.html">German</ulink>, <ulink url="index.it.html">Italian</ulink>, <ulink url="index.ru.html">Russian</ulink>, and <ulink url="index.ja.html">Japanese</ulink>. <!-- TODO: Maybe better: "This document has originally been written in English. Translations into different languages are available." --> </para> Again, links are correct and point to index.{fr,de,it,ru,jp}.html. And the same holds for any translation. Broken links are only in developers-reference published on the Debian's website. Since links in the source code and in the developers-reference package are correct, then it is the content negotiation problem. Looks like the webserver incorrectly rewrites links. Let me stress that my report is _not_ about links to English, or links in English. It is about _broken_ links in _any_ developers-reference as published on the Debian's website. So, my bug report is about www.debian.org, not developers-reference. Please, reconsider it and reassign #912724 to www.debian.org. Regards, Lev
