When I am trying to upgrade my Magento version from 2.1.7 CE to 2.2.0 CE, through composer update, I am getting the following error.

Problem 1 - magento/module-wishlist-sample-data 100.1.0-rc1 requires magento/module-wishlist 100.1.* -> satisfiable by magento/module-wishlist[100.1.0-rc1, 100.1.0-rc2, 100.1.0-rc3, 100.1.0, 100.1.1, 100.1.2, 100.1.3, 100.1.4, 100.1.5, 100.1.6]. - magento/module-wishlist-sample-data 100.1.0-rc2 requires magento/module-wishlist 100.1.* -> satisfiable by magento/module-wishlist[100.1.0-rc1, 100.1.0-rc2, 100.1.0-rc3, 100.1.0, 100.1.1, 100.1.2, 100.1.3, 100.1.4, 100.1.5, 100.1.6]. - Can only install one of: magento/module-wishlist[101.0.0, 100.1.0-rc1]. - Can only install one of: magento/module-wishlist[101.0.0, 100.1.0-rc2]. - Can only install one of: magento/module-wishlist[101.0.0, 100.1.2]. - Can only install one of: magento/module-wishlist[101.0.0, 100.1.3]. - Can only install one of: magento/module-wishlist[101.0.0, 100.1.4]. - Can only install one of: magento/module-wishlist[101.0.0, 100.1.5]. - Can only install one of: magento/module-wishlist[101.0.0, 100.1.6]. - magento/product-community-edition 2.2.0 requires magento/module-wishlist 101.0.0 -> satisfiable by magento/module-wishlist[101.0.0].

Here is my composer.json file, located in my project's root folder.

Anyone know, how to fix this ?

Reset to default

You need to also update the sample data because it is installed for Magento 2.1 specifically. Alternatively remove it if you do not need it anymore.

This is what worked for me in a previous update:

  1. Reset sample data:

    bin/magento sampledata:reset

  2. Remove the sample data modules from composer.json:

    "magento/module-bundle-sample-data": "100.1.*", "magento/module-theme-sample-data": "100.1.*", "magento/module-catalog-sample-data": "100.1.*", "magento/module-tax-sample-data": "100.1.*", "magento/module-customer-sample-data": "100.1.*", "magento/module-cms-sample-data": "100.1.*", "magento/module-widget-sample-data": "100.1.*", "magento/module-catalog-rule-sample-data": "100.1.*", "magento/module-sales-rule-sample-data": "100.1.*", "magento/module-sales-sample-data": "100.1.*", "magento/module-grouped-product-sample-data": "100.1.*", "magento/module-downloadable-sample-data": "100.1.*", "magento/module-msrp-sample-data": "100.1.*", "magento/module-configurable-sample-data": "100.1.*", "magento/module-product-links-sample-data": "100.1.*", "magento/module-wishlist-sample-data": "100.1.*", "magento/module-review-sample-data": "100.1.*", "magento/module-swatches-sample-data": "100.1.*", "magento/sample-data-media": "100.1.*", "magento/module-offline-shipping-sample-data": "100.1.*"

  3. Run composer update

  4. Reinstall sample data:

    bin/magento sampledata:deploy

  • When I run the composer update, I got the output as follows, Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Package fabpot/php-cs-fixer is abandoned, you should avoid using it. Use friendsofphp/php-cs-fixer instead. Generating autoload files Commented Oct 27, 2017 at 9:48
  • Did you really update the version number in composer.json to 2.2.0? Maybe that got reverted after your unsuccessful update Commented Oct 27, 2017 at 15:10
  • Yea, that was the issue. Now it's working fine. Thanks a lot :) Commented Oct 28, 2017 at 14:07
