We cannot retrieve information on magento/product-community-edition - System upgrade Web GUI

[MirkoHufnagel]

Hi,

i receive the fallowing error on the System upgrade Web GUI:

"We cannot retrieve information on magento/product-community-edition."

An update on the console works without problems.

However, I would like to fix this bug as well. The known problem with allow_url_fopen in the PHP configuration does not exist for me. Both php-fpm and cli have this set to On.
I'm using Magento 2.2.8 and 2.2.10 (error occurs with both versions) on nginx and PHP 7.0.33.

Thanks in advance.

Mirko

Hi @MirkoHufnagel 

Can you try to upgrade Magento using CLI:

composer require magento/product-community-edition 2.1.4 --no-update
composer update
rm -rf var/cache/* var/page_cache/* var/generation/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile

You can also check this link http://devdocs.magento.com/guides/v2.0/comp-mgr/cli/cli-rc1-samp.html

Thanks

As I already wrote - the update on the console (CLI) works. But I would also like to understand and correct this error.

Hello @MirkoHufnagel 

Did you ask hosting guys about

allow_url_fopen in the PHP configuration

They generally help with this in case you have unmanaged server.

If they don't try following these

https://www.a2hosting.in/kb/developer-corner/php/using-php.ini-directives/php-allow-url-fopen-direct...

Hi @MirkoHufnagel 

As you are using nginx server so you cannot do it using .htacess file.

You can edit the settings in php.ini using below command.

sudo nano /etc/php/7.1/fpm/php.ini

Instead of 7.1 you can use your current php version.

Then edit the file and make 

allow_url_fopen = On

After changing create a info.php file on your root directory with following code in it.

<?php 

phpinfo();

?>

Run this file and search for "allow_url_fopen" and it should have its value 1.

Hope it helps!

Thanks

Hi guys

I really appreciate your help. But have you read my original posting? (or did I write it so stupidly). :-)

The url fopen parameter is on.

Any other ideas?
