As a WordPress developer, I can help you fix the “Update failed: Download failed. Destination directory for file streaming does not exist or is not writable” issue. Based on the provided web search results, there are a few possible solutions you can try:
- Check and modify the wp-config.php file: Open the wp-config.php file and search for a line containing a constant called ‘WP_TEMP_DIR’. If you find this line, update it to the following:
define('WP_TEMP_DIR', ABSPATH . 'wp-content/tmp');If the line doesn’t exist, you can add the above line anywhere before the line containing “/* That’s all, stop editing! Happy publishing. */”. Save the file and try to update WordPress again[7].
If there’s another definition of the temp directory further down in the wp-config.php file, make sure to either change it to the above or delete it[11].
- Create a temporary folder and set permissions: If the above solution doesn’t work, you can create a new folder named ‘tmp’ inside the ‘wp-content’ directory. Ensure that the folder permissions are set to 755. This should make the directory writable and allow the update process to proceed[8].
- Check file and directory ownership: Make sure that the files and directories in your WordPress installation are owned by the correct user (usually the web server user). Incorrect ownership can cause issues with file permissions and lead to errors like this one. You can contact your hosting provider for assistance with this step if you’re unsure how to check or change file ownership.
If you’ve tried these solutions and are still encountering issues, consider reaching out to your hosting provider or the WordPress support forums for further assistance.
