Fix WordPress Download failed errors on update
If you run into problems trying to update WordPress, it could be caused by the temporary directory WordPress attempts to use. You can easily fix this by defining a WP_TEMP_DIR in your wp-config.php file.
WordPress update failing
If you're trying to upgrade WordPress itself, you might encounter this error:
Download failed.: Destination directory for file streaming does not exist or is not writable.
WordPress plugin update failing
If you were trying to update a WordPress plugin, you might have encountered this error:
An error occured while updating (Plugin Name). Download failed. Destination directory for file streaming does not exist or is not writable.
Define a WP_TEMP_DIR in your wp-config.php file
If you've encountered issues trying to update WordPress, you can simply follow the steps below to resolve them.
Open you wp-config.php file with the cPanel File Manager Code Editor
You should see this code towards the top of the file:
* @package WordPress */ // ** MySQL settings - You can get this info from your web host ** // /** The name of the database for WordPress */ define('DB_NAME', 'anotherd_wrd1');
You want to add a definition for WP_TEMP_DIR using the ABSPATH WordPress variable pointing to your WordPress install path, followed by wp-content/ so that when WordPress needs to temporarily write files to the server, it can use this writable directory to do so.
You want to place this definition of define('WP_TEMP_DIR', ABSPATH . 'wp-content/'); in-between the lines mentioned above, and it would end up looking like this when you've completed it:
* @package WordPress */ define('WP_TEMP_DIR', ABSPATH . 'wp-content/'); // ** MySQL settings - You can get this info from your web host ** // /** The name of the database for WordPress */ define('DB_NAME', 'anotherd_wrd1');
Now Save your wp-config.php file.
Try to update WordPress again, if for some reason it is still failing, be sure to check file permissions on your wp-content folder, and ensure it's set to 755 so that the server can write to it.
