I am having troubles updating Drupal from composer.

Running composer update gives med this error, that I need help to interpret:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1

- don't install drupal/core 8.6.3|remove drupal/drupal dev-master



- don't install drupal/core 8.6.x-dev|remove drupal/drupal dev-master



- don't install drupal/core 8.7.x-dev|remove drupal/drupal dev-master



- Installation request for drupal/drupal dev-master -> satisfiable by drupal/drupal[dev-master].



- Installation request for drupal/core ^8.6.3 -> satisfiable by drupal/core[8.6.3, 8.6.x-dev, 8.7.x-dev].

My composer.json file looks like this:
