Failed to upgrade wordpress-4.5.1

This is because when upgrading WordPress, WordPress will be in the database WP_ Add core to options table_ updater.lock record. If you interrupt the upgrade of WordPress, the record will be left in the database. When the next upgrade, WordPress detects the existence of this record and returns “another update in progress.”. It can be solved by the following methods:

Method 1, through MySQL database management tools (such as phpMyAdmin), in WP_ Find the core in the options table_ updater.lock Record and delete this column of data.

Method 2: log in the database through the terminal, assuming that the prefix of the table is WP_ The database is WordPress

mysql -u root -p
use wordpress;
select * from wp_options where option_name='core_updater.lock';

mysql -u root -puse wordpress;select * from wp_ options where option_ name=’core_ updater.lock ‘;

delete from wp_options where option_name='core_updater.lock';

delete from wp_ options where option_ name=’core_ updater.lock ‘;

Refresh the update page, you can upgrade!
