This problem was the first time that Chiang was encountered. When the old Jiang tribe was preparing to select WordPress for automatic upgrade, an error message "another update in progress" was displayed, indicating that the upgrade to the latest version could not be performed. Some netizens also encountered this problem through searching, probably because the database tables were occupied during the last upgrade and the locked link could not continue.
1. Errors
It should be because a table in the database table is locked and the database cannot continue.
2. Solve the problem
1. Log on to the PHPMyAdmin client, open the wp_options data table, and find the core_updater.lock field.
2. Locate the field and delete it.
Finally, the error message "another update is in progress" is not displayed after we upgrade WordPress. The problem is solved.
