I am upgrading from Magento 2.1.14 to Magento 2.2.6, when I run composer update I get the following error. Appreciate your help.

Problem 1 - Installation request for magento/product-community-edition 2.2.6 -> satisfiable by magento/product-community-edition[2.2.6]. - magento/product-community-edition 2.2.6 requires zendframework/zend-stdlib ^2.7.7 -> no matching package found.

Potential causes: - A typo in the package name - The package is not available in a stable-enough version according to your minimum-stability setting see https://getcomposer.org/doc/04-schema.md#minimum-stability for more details. - It's a private package and you forgot to add a custom repository to find it

Please update the zendframework/zend-stdlib version in your magento_root_dir/composer.json to what the error shows, i.e. "zendframework/zend-stdlib": "^2.7.7" and then run composer update command.
