TYPO3 Core

For activated extensions TYPO3 tries to download these non-existant files with v9 in url:
https://extensions.typo3.org/fileadmin/ter/a/b/about-l10n/about-l10n-de.v9.zip
https://extensions.typo3.org/fileadmin/ter/b/a/backend-l10n/backend-l10n-de.v9.zip
etc.
These urls are working with v7 and v9.

For deactivated extensions TYPO3 succesful downloads these files without v9 in url:
https://typo3.org/fileadmin/ter/f/i/filemetadata-l10n/filemetadata-l10n-de.zip
https://typo3.org/fileadmin/ter/f/o/form-l10n/form-l10n-de.zip

Url is generated here: https://github.com/TYPO3/TYPO3.CMS/blob/1ad185f32e63179dabb6d9634c1cd5c75bad51fb/typo3/sysext/lang/Classes/Service/TerService.php#L180-L188

These urls are working with v7 and v9.
->
These urls are working with v7 and v8.

So, as far as I can see, the urls are correct, the translations are just not yet populated in a v9 version. I'll ping Xavier about that, maybe he knows details.

For the detail that it works with 'deactivated' extensions, this is because the em does not know the version of the not loaded extension and thus fetches a very old 'compatibility' version of the localizations, which is not cool, either. I think the language module shouldn't fetch translations of not loaded exts at all.

Did you reach Xavier? The files are still not there.

This boiled down to a server-team issue. They promised to fix that now, so for installed packages, the v9 versions are hopefully available soon.

However, the language BE module currently loads very old localization packages for not installed extensions. I'll now push a patch (tested on v7, v8 and v9) to only fetch localization packages of actually loaded extensions - for not loaded extensions the version detection goes wrong, so to prevent old l10n information, we just skip downloading packages of not loaded extensions with my patch.

For v9, i hope the server team fixes the issue soon, and the module will receive a revamp and relocation anyway - I'm currently just a bit blocked by the server-team issue.

ok, server team solve the main issue meanwhile, so v9 language packs are now available again. kudos to stucki for this.
