Followed the commands below to upgrade Magento 2.2.0, I am on 2.1.9
composer require magento/product-enterprise-edition 2.2.0 --no-update composer update magento/product-enterprise-edition 2.2.0
I am getting the following error message.
./composer.json has been updated 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 - Can only install one of: magento/framework-foreign-key[100.2.0, 100.1.3]. - Can only install one of: magento/framework-foreign-key[100.2.0, 100.1.3]. - Can only install one of: magento/framework-foreign-key[100.1.3, 100.2.0]. - magento/product-enterprise-edition 2.2.0 requires magento/framework-foreign-key 100.2.0 -> satisfiable by magento/framework-foreign-key[100.2.0]. - Installation request for magento/product-enterprise-edition 2.2.0 -> satisfiable by magento/product-enterprise-edition[2.2.0]. - Installation request for magento/framework-foreign-key (locked at 100.1.3) -> satisfiable by magento/framework-foreign-key[100.1.3]. Installation failed, reverting ./composer.json to its original content.
What is magento/framework-foreign-key? Is there anything that needs to be done prior to upgrade?
