For updating your database, Mediawiki also has a pointer to add /mw-config/ to the end of your URL (i.e. https://myfreedombox.com/mediawiki/mw-config/)
This will take you to an installation page that will automatically update your database. On the road, for security reasons, the page will ask for an “upgrade key.” You may reach this key with sudo cat /etc/mediawiki/LocalSettings.php | grep wgUpgradeKey
