  • It's core_updater.lock, with a dot not an underscore, but that is where this error comes from: it only checks the lock.

  • Actually I guess there is another option: you don't have permission to make a new row in wp_options? (Or it's being rejected by some DB trigger?) OK, then you need to debug these two places: Core_Upgrader, which checks the lock and generates the error, and WP_Upgrader create_lock. I'd start by adding error_log() calls just before the two return falses to see which is being hit.

  • Modify your create_lock function to look like this: gist.github.com/RupW/ee7be1ae8f8da5b6b37e942283879398 All of the error_log lines are new but the rest should be the same. Then try to update again and check your server or PHP error log to see what happened.

In my case the problem was caused by bad import of MySQL tables in phpMyAdmin.

(I exported databases instead of only one database's content. While importing MySQL errored with "Cannot create DB" but created the tables.)

Testing INSERT INTO wp_options ( option_name, option_value, autoload ) VALUES ('core_updater.lock', 1592768373, 'no') (thanks @Rup) said I have a duplicate primary key.

If moving a wp installation is your issue, export the old data in a propper way (click database, then export), drop tables and import the new sql file.
