Upgrade fails !!

[rbuelund]

When trying to manually upgrade PrestaShop from 1.7.4.4 to 1.7.5.2 it fails with this error:

Fatal error: Uncaught Symfony\Component\DependencyInjection\Exception\RuntimeException: Invalid service "prestashop.module.link_block.cache": class "PrestaShop\Module\LinkList\Cache\LegacyLinkBlockCache" does not exist. in /var/www/www.xxxx-dev.dk/www/shop/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/AbstractRecursivePass.php:123 Stack trace: #0 /var/www/www.xxxx-dev.dk/www/shop/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/AbstractRecursivePass.php(150): Symfony\Component\DependencyInjection\Compiler\AbstractRecursivePass->getConstructor(Object(Symfony\Component\DependencyInjection\Definition), true) #1 /var/www/www.xxxx-dev.dk/www/shop/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/ResolveNamedArgumentsPass.php(50): Symfony\Component\DependencyInjection\Compiler\AbstractRecursivePass->getReflectionMethod(Object(Symfony\Component\DependencyInjection\Definition), '__construct') #2 /var/www/www.xxxx-dev.dk/www/shop/vendor/symfony/sy in /var/www/www.xxxx-dev.dk/www/shop/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/AbstractRecursivePass.php on line 123

 

I followed this description: https://devdocs.prestashop.com/1.7/basics/keeping-up-to-date/upgrade/

 

This is really frustrating that it is SO hard to upgrade PrestaShop - this should just work !!! That makes me think about switching to another shop system !

Your problem come from a module (ps_linklist) not from Prestashop in this case.

Moreover, clear cache manually : delete all folders and files in /var/cache/ it will be regenerated.

[rbuelund]

Moved it to the english forum. Deleting var/cache did not help.

[Janett]

Remove module ps_linklist

Have you tried to use the 1-click-Upgrade module instead? Make sure to use the lastest version

[rbuelund]

But is ps_linklist not a "core" module of prestashop ? Why should I remove it - it is in use. Should it not also upgrade automatically ?? The ps_linklist module is version 2.1.6 in my installation.

[Janett]

Delete the current ps_linklist module on your ftp, but do not uninstall it to not lose your associated data.

Check if error disappeared.

Try to get the lastest version of this module 3.0.3 : https://github.com/PrestaShop/ps_linklist/releases

If I remove the folder ps_linklist - yes, then the upgrade runs - but how do I get the module back again afterwards ??

[rbuelund]

Finally got it working! 

What I did:

1) Set PHP version to 7.1.5

2) Deleted all files in folder modules/ps_linklist

3) Upgraded with 1-click (latest version)

4) Under modules - upgraded Linklist module to 3.0.3

5) Changed to PHP version 7.3.5

Warning ! Prestashop is not compliant with PHP 7.3 : https://devdocs.prestashop.com/1.7/basics/installation/system-requirements/

You can follow work in progress about support of PHP 7.3 here : https://github.com/PrestaShop/PrestaShop/issues/12461

Ok - downgraded to 7.1.5 and everything still works.

Lifesaver. Thanks!
