Update failed: The update cannot be installed because some files could not be copied. This is usually due to inconsistent file permissions.

If you are using the Bitnami WordPress stack, the file permissions might be causing the update issue. To fix it, you can follow these steps:

  1. Connect to your server using SSH or any other preferred method.
  2. Navigate to the WordPress installation directory. In Bitnami, it is usually located at /opt/bitnami/apps/wordpress/htdocs/.
  3. Run the following command to set correct file permissions for the WordPress files:shell
sudo chown -R bitnami:daemon . 
sudo find . -type d -exec chmod 775 {} \; 
sudo find . -type f -exec chmod 664 {} \; 
  • This command changes the ownership to the bitnami user and the daemon group, and sets the appropriate file permissions.
  • After running the above commands, try the update process again from the WordPress admin dashboard or by following the standard WordPress update procedure.

By setting the correct file ownership and permissions, you should be able to update WordPress without encountering the “files could not be copied” error.

Note: The bitnami user and daemon group are the default user and group used in the Bitnami WordPress stack. If you have customized your setup or are using a different user, make sure to replace bitnami with the correct username in the above commands.

If you continue to experience difficulties with the update process, you might consider reaching out to the Bitnami support team or consulting their documentation for further assistance with updating WordPress in the Bitnami environment.
