Magento – Unable to upgrade to Magento 2.1.0 GA via command line

composermagento-2.1magento2upgrade

I've already applied the patch MDVA-532.

When I run composer update magento/magento-composer-installer I got this error:

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

Problem 1
– The requested package magento/product-community-edition == 2.0.6.0 could not be found.

Problem 2
– Installation request for braintree/braintree_php == 2.39.0.0 -> satisfiable by braintree/braintree_php[2.39.0].

– Conclusion: don't install braintree/braintree_php 3.7.0
– Installation request for magento/product-community-edition 2.1.0 -> satisfiable by magento/product-community-edition[2.1.0].

I've bumped into the same issue. Any attempt to upgrade to version 2.1 bumped into various messages like "Conclusion: don't install magento/module-widget" or "Can only install one of". Closer inspection of all packages defined in my composer.json showed that it was calling for various modules of version 100.0.* while actually the upgrade messages mentioned that version 100.1.x was needed.

I changed all instances of 100.0.* to 100.* and this allowed me to upgrade.

Note that I assume that this versioning scheme follows the semantic versioning standards, meaning that this allows me to upgrade to newer minor versions without breaking backwards compatibility. Also note that I've run this on various development sites, where I'm just developing Magento 2 extensions. I don't have any Magento 2 project, so don't care much about the core. It might be that my composer.json hacks are not meant for production.

Magento 2.1 Composer – Update Error: magento/product-community-edition Requires Specific PHP Versions

There is no magento/product-community-edition 2.1.0 yet. Latest release is magento/product-community-edition 2.1.0-rc3. The wording in magento bulletins and notifications is misleading and tricky. You get the impression that there is a 2.1.0 GA, but there are only Release candidates.

Magento2.3 Upgrade – How to Upgrade from Magento 2.2.6

Solved using following steps:

Come back to the previous version of composer.json Following instruction from How to Upgrade magento version from 2.2.X to 2.3.0?

In the last step, it says: sjparkinson/static-review is not required in your composer.json and has not been removed fabpot/php-cs-fixer is not required in your composer.json and has not been removed

Run: # composer upgrade

Then you can get errors like this when you try to do:

php bin/magento setup:upgrade ... Class 'Zend\Mvc\Controller\LazyControllerAbstractFactory' not found ...

So you must to edit the composer.json file and modify the autoload section:

"autoload": {
    "psr-4": {
        "Magento\\Framework\\": "lib/internal/Magento/Framework/",
        "Magento\\Setup\\": "setup/src/Magento/Setup/",
        "Magento\\": "app/code/Magento/",
        "Zend\\Mvc\\Controller\\": "setup/src/Zend/Mvc/Controller/"
    },
},

Then run: > composer dumpautoload

And rerun: > php bin/magento setup:upgrade

And it works!
