Magento 2 Upgrade – Fix Composer Error from 2.1.6 to 2.1.7

composermagento2upgrade

I am trying to upgrade from Magento 2.1.6 to 2.1.7 using this https://stackoverflow.com/documentation/magento2/9022/upgrading-magento#t=201704130958117574309 as my guide.

I type in- composer require magento/product-community-edition 2.1.7 --no-update

Then the next step when I run composer update I get this error-

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

Problem 1
– The requested package magento/project-community-edition 2.1.6 is satisfiable by magento/project-community-edition[2.1.6] but these conflict with your requirements or minimum-stability.

What is causing this error?

@RamaChandran I followed the link you mentioned and tried this

"repositories": [
    {
        "type": "composer",
        "url": "http://packages.magento.com/"
    }
]

When I do that I get this error

[Composer\Downloader\TransportException]
Your configuration does not allow connections to http://packages.magento.com/packages.json. See https://getcomposer.org/doc/06-config.md#secure-http for details.

I switched the url to https and now get this error-

[Composer\Downloader\TransportException]
The "https://packages.magento.com/packages.json" file could not be downloaded: php_network_getaddresses: getaddrinfo failed: Name or service not known
failed to open stream: php_network_getaddresses: getaddrinfo failed: Name or service not known

Your require section is conflicting with your current package name (and is being a bit recursive).

First, let's peg your composer project version to the next version number:

"version": "2.1.7",

Then update your require section:

"require": {
    "magento/product-community-edition": "2.1.7",
    "composer/composer": "<=1.0.0-beta1",
    "magento/data-migration-tool": "2.1.7",
},

You don't need to require magento/project-community-edition - that's the name of the project you're attempting to update. See: "name": "magento/project-community-edition". You're also loading an out-of-date magento/data-migration-tool but I'd guess you've already done the migration. You may be able to remove this entry as well. Finally, the core Magento repos suggest the <=1.0.0-beta1 version for composer/composer so we should probably stick to that.

Under your "repositories" the second

"magento": {
    "type": "composer",
    "url": "https://repo.magento.com"
}

is extraneous and can be removed.
