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

Hi all,

I'm having problems upgrading my drupal 7.58 to 8.8.0 using composer by the command:

php composer.phar update drupal/core --with-dependencies

It says it will take a long time and then I get this error message:This dependency has been included more than once in the dependencies list of one or more packages, or the package is not available for a stable release.

If you encounter this problem, you can edit composer.json to remove the offending package version, so it won't be included again when you run update next time. Lag Ja Gale Lyrics , Breathless lyrics
