I have tried to upgrade Magento CE from 2.4.3 to 2.4.3-p1 using the following commands:

composer require magento/product-community-edition=2.4.3-p1 --no-update composer update

but I am getting this error:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires magento/product-community-edition 2.4.3-p1, found magento/product-community-edition[0.42.0-beta7, 2.0.0, ..., 2.4.3] but it does not match the constraint.

Any help would be appreciated.


  • try this command with "composer update" with iniatl composer.json and lock file than use the require command . I faced similar issue this will update alll the modules for 2.4.3
