Question

Whenever I tried to Update my wordpress it shows Error

The Error is:

**Downloading update from https://downloads.wordpress.org/release/wordpress-5.7.1-new-bundled.zip…

The authenticity of wordpress-5.7.1-new-bundled.zip could not be verified as no signature was found.

Unpacking the update…

The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php

Installation failed.**

Please help, I appreciate any help from you…

Hi there,

It sounds like that the user that the Apache service is running as does not have permissions to your WordPress core files.

What you could do is set the ownership of the files to the Apache user.

If you have not changed the Apache user you could run the following command:

sudo chown -R www-data:www-data /var/www/html

If you have changed the user, you would need to change the www-data:www-data part with the user that you are using.

Let me know how it goes. Regards, Bobby

Hello, @newwayelegant

I will recommend checking the ownership of the /var/www/html directory as per @bobbyiliev comment.

Also, check the permissions of the files and the directories in the public_html folder.

I’m not sure but here are some ideas, Try upgrade from wp CLI command or increase the memory if possible, similar case, https://wordpress.org/support/topic/5-6-update-critical-error/page/2/
