Update failed: Could not create directory

That indicates your site’s folder has a permission issue.

1. Connect to your WordPress site using an FTP client or the file manager provided by your web hosting control panel.
2. Navigate to the root folder of your WordPress installation. The root folder contains folders such as “wp-content,” “wp-includes,” and “wp-admin.”
3. Change the permission of the “wp-content,” “wp-includes,” and “wp-admin” folders to 755.
4. Change the permission of all the files inside these folders to 644.
5. Change the permission of the root folder to 755.
6. Change the permission of the “wp-config.php” file to 644.
7. If you have a custom plugin or theme installed, change the permission of those folders to 755 and the files inside those folders to 644.
8. If you are still experiencing issues, you can try setting the permission of all folders to 775 and all files to 664. However, remember that this can be a security risk and should only be done as a last resort.
9. It is generally a good idea to keep the permissions as restricted as possible to improve security.

I hope this helps! Let me know if you have any other questions.
