Drupal: update.php error

I'm copying my Drupal installatio开发者_如何学运维n to another folder and I've copied the related database.

When I run update.php on the new copy I get the following error:

http://dl.dropbox.com/u/72686/updateError.png

should I disable some modules.. or is something about Drupal core ?

(I'm using version 6.16)

I've flushed all caches and the website is offline.

thanks

You have to log in to run update.php... actually I'm also wondering how could you run update.php without being logged as administrator O_O

For the error... looking at the line reported in the error:

list($module, $version) = array_pop(reset($_SESSION['updates_remaining']));

you can see the use of $_SESSION array;

Probably you don't have any php sessions if you are not logged in...
