It gives below error

Instead of GUI i'm using CLI.

How to update Magento2 using composer

I'm using @Mukesh Chapagain Solution

Updating/Upgrading to Magento 2.X.X (via composer) Latest is 2.1.1

composer require magento/product-community-edition 2.X.X --no-update
composer update //If your receive out of memory error then in apache php.ini please update your memory_limit 7680000M Example
rm -rf var/di var/generation
php bin/magento cache:flush
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento indexer:reindex

After upgrade, check your Magento version with the following command:

php bin/magento --version

Worked for me :) Why it doesn't work with GUI?

  • The path that it says is non-writable: is it, as it claims, non-writable by the user you are installing as? Commented Oct 14, 2016 at 2:57
  • HI @DewiMorgan It's plugin. What permission needs to be set? Currently app folder has 770 permission

  • Who owns it, and what's the group? I don't know Magento well enough to say for sure, but on a WAMP system I suspect it's running as user Apache. If the owner and group are, say, root, then 770 won't do anything, but it'd work fine from the commandline. This is just a guess, though, I'm reasonably ignorant on this I am afraid.

  • Also, it's the app/code folder (and subfolders) that it's complaining about, not the app folder. Commented Oct 15, 2016 at 6:05

Bug: Magento 2 checks the .update_cronjob_status file but never generates it.

Please check this answer on the Magento community website.

Readiness Check failing due to Cron script readiness check failed


This Issue generates because of cron is not set up.so run this command php bin/magento cron:install
