Update from 12.0.0 to 12.0.2

I’m trying to update our nextcloud, but no matter what option I use get the same response:
“'Updates between multiple major versions and downgrades are unsupported.”

This is the result when I use the update.phar.

/var/www/nextcloud/updater# sudo -u www-data php updater.phar
