for the turkish language pack "manifest.php" file is wrong. I edit this file outside of zip and replaced this file in the zip file. then I tried once again, it was successful.
translators made big mistake for that.
manifest.php file should be like this:
<?PHP
/******************************************
* SuiteCRM Translations
* @URL: https://crowdin.com/project/suitecrmtrans
* @author SuiteCRM Community via Crowdin
******************************************/
$manifest = array(
'name' => 'Turkce (Turkiye)',
'description' => 'Çeviri: www.crowdin.com/project/suitecrmtranslations',
'type' => 'langpack',
'is_uninstallable' => 'Yes',
'acceptable_sugar_versions' =>
array (),
'acceptable_sugar_flavors' =>
array('CE'),
'author' => 'SuiteCRM Community',
'version' => '7.9.1.0',
'published_date' => '2017-06-19',
);
$installdefs = array(
'id'=> 'tr_TR',
'image_dir'=>'<basepath>/images',
'copy' => array(
array('from'=> '<basepath>/include','to'=>'include'),
array('from'=> '<basepath>/modules','to'=>'modules'),
array('from'=> '<basepath>/install','to'=>'install'),
)
);
?>
