Problems updating to 4.2.1

I have now updated thirty WordPress websites to 4.2.1 and all of them give errors.

Below the error I receive.
[code]
Call to undefined method wpdb::get_col_length() in \wp-admin\includes\upgrade.php on line 1450
[/code]
[code]
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 65488 bytes) in \wp-admin\includes\file.php on line 159
[/code]
[code]
Fatal error: Maximum execution time of 30 seconds exceeded in \wp-includes\class-http.php on line 1597
[/code]

The allowed memory on php,ini is 256Mb and on WordPress 128Mb

It look like the update requires that the default templates and plugins of WordPress must be installed.

Also the update hangs on unpacking the zip.

I now have manually copied the update. But I hope this is solved the next update.
