I upgraded several sites thus far without issues, but somehow on the latest update I get this error:
The following updates returned messages
system module
Update #7053
Failed: PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'user-menu' for key 1: INSERT INTO {menu_custom} (menu_name, title, description) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2); Array ( [:db_insert_placeholder_0] => user-menu [:db_insert_placeholder_1] => User Menu [:db_insert_placeholder_2] => The User menu contains links related to the user's account, as well as the 'Log out' link. ) in system_update_7053() (line 2408 of /modules/system/system.install).
I checked the forums but couldn't really locate any solution, perhaps I missed something. Basically there are 19 updates left, the rest went fine.
Below the list of updates that needs to be done:
system module
7053 - Upgrade standard blocks and menus.
7054 - Remove {cache_}.headers columns.
7055 - Converts fields that store serialized variables from text to blob.
7057 - Increase the size of session-ids.
7058 - Remove cron semaphore variable.
7059 - Create the {file_usage} table.
7060 - Create fields in preparation for migrating upload.module to file.module.
7061 - Migrate upload.module data to the newly created file field.
