I have to develop features for an old project stuck on drupal 8.5, so I figured out it would be great to update the core version to at least 8.8 for a start. The project is setup using composer and drush, so I started following the steps listed in https://www.drupal.org/docs/updating-drupal/migrating-the-composer-project-for-drupal-earlier-than-880 But I'm stucked with an error in "Migrating from drupal-composer/drupal-scaffold to drupal/core-composer-scaffold"
This is the initial composer.json

Running the first step (Migrating from webflo/drupal-core-require-dev to drupal/core-dev) was pretty strait forward but from the second I'm stuck with an error as I run composer require drupal/core-composer-scaffold:^8.8

I'm considering giving up on the upgrade since this is only the beginning and it should be the easy part since I don't have to handle the database yet.
How do I fix these errors?
