Comment 5 for bug 214998

already done. :) I'm one of them.

language-support-$lang is a meta package containing dependencies for additional useful packages for a $lang environment.
For example, if there would be a myspell-fur or a openoffice-l10n-fur package, they would go in there.
As we don't have such packages, a language-support-fur meta package makes no sense.

language-packs and language-support packages are generated by script. So the bug is that the script missed that the locale fur_IT.UTF-8 is indeed available.
