I have a problem - when I click on "Wordpress update", I receive this message:

Downloading update from https://downloads.wordpress.org/release/wordpress-5.1-new-bundled.zip… 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

I changed permissions: WP-admin and WP-includes to 755 WP-content to 777 All files in WP-admin are 755.

What can be the problem? I am trying to solve it, but I can't do it.

  • The permissions need to be set for wp-content and wp-content/upgrade for the zip download and unpack. WordPress should then also be able to write to all WordPress core files in web root, wp-admin and wp-includes. Permissions need to be set for both files and folders. – MikeNGarrett Mar 1 at 14:39
  • It can sometimes also have to do with who "owns" the files. This may give you some ideas: stackoverflow.com/questions/18352682/… – WebElaine Mar 1 at 14:40
