This message is shown when you update directly from within WordPress. It happens when an update failed (or still is in progress) and you can’t start another update.

This message should automatically disappear in 15 minutes or when the update process has finished, but sometimes it gets stuck.

• Wait at least 15 minutes and try again.
• If the issue persists, check if there is a .maintenance file in the WP root folder, delete it and try again.
• If the issue persists, open the wp_options table with phpMyAdmin and search for core_updater.lock. If it’s found (in option_name), delete the row.
• You should now be able to update again.

SELECT * FROM `wp_options`
WHERE `option_name` like "core_updater.lock"
