I have installed Magento 2 CE Version 2.1.0. I'm doing System Upgrade on my Linux Server

It gives below error

enter image description here

[UPDATE]

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? – Dewi Morgan Oct 14 '16 at 2:57
  • HI @DewiMorgan It's plugin. What permission needs to be set? Currently app folder has 770 permission – Ankit Shah Oct 14 '16 at 3:24
  • 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. – Dewi Morgan Oct 15 '16 at 6:02
  • Also, it's the app/code folder (and subfolders) that it's complaining about, not the app folder. – Dewi Morgan Oct 15 '16 at 6:05
