Hi I am trying to update my Shopware version from 5.1.6 to 5.2.1 and I am getting lots of error.

1. First of all it failed at data migration, then I have reinstalled my site from Back up&nbsp;

2. Now Data Migration is finished and in the last part I am getting this message.&nbsp; **"** \*\* Fatal error\*\*: Declaration of Shopware\Components\DependencyInjection\Container::reset() must be compatible with Symfony\Component\DependencyInjection\ResettableContainerInterface::reset() in\*\*/var/www/clients/client1/web8/web/engine/Shopware/Components/DependencyInjection/Container.php **&nbsp;on line&nbsp;** 35 \*\ ***"**

&nbsp;

**Any Help or Tip&nbsp;would be appreciated.**

&nbsp;

**Thank You**
