When updating from 2.2.2 to 2.2.3 with
composer require magento/product-community-edition 2.2.3 --no-update
I get this error:
[InvalidArgumentException] Could not find package magento/product-community-edition in a version match ing 2.2.3
I've checked this and I couldn't reproduce your error. Could you maybe extend your question with more details. Like what you've done already. If you have this with both an existing project and a clean Magento 2.2.2 installation?
