Problem upgrading to Drupal 8.8.0

Hello, i have bought and installed Nation theme. If i install the demo version it works fine with its Drupal 8.6.9 version. If i try to upgrade to 8.8.0 version (deleting core and vendor folders), i get a
"Fatal error: Interface 'CommerceGuys\Addressing\AddressInterface' not found in /Library/WebServer/Documents/nation/modules/contrib/address/src/AddressInterface.php on line 11"

Which is the correct way to upgrade to latest Drupal version? Thanks in advance and greetings


The drupal core 8.x require to update the address first. You should install composer and install address require using this "composer require "drupal/address ~1.0" And then you can continues to update drupal core
