"Failed: ALTER TABLE {views_view} ADD UNIQUE KEY name (name)" [5.x-1.6 to 6.x-2.5]

Running update.php, I received the following error messages:

user warning: Duplicate key name 'name' query: ALTER TABLE live_views_view ADD UNIQUE KEY name (name) in /my/path/to/website/beequu6/includes/database.mysql-common.inc on line 403.

and

Failed: ALTER TABLE {views_view} ADD UNIQUE KEY name (name)

Would you please be so kind to look into it?

Thanks
