Hi @alexis_turruell,

Make sure that you have installed install the sodium php extension.

For reference:

I hope it will help you!

I installed

php-pecl-libsodium2 x86_64 2.0.22-1.el7.remi.7.1

the error persist:

Module 'Magento_EncryptionKey':

Have you restrarted the server after installing extension?

[alexis_turruell]

Yes, I did. Nothing.

@alexis_turruell  If not the libsodium then it could be redis. Try cleaning the redis cache.

composer require magento/product-community-edition 2.3.x --no-update (You already did this)
composer update
rm -rf var/di/* var/generation/* var/cache/* var/page_cache/*
redis-cli flushdb
php bin/magento setup:upgrade

[alexis_turruell]

Yes I did before (composer, Clear the var/ and generated/ subdirectories:, redis-cli flush).

redis-cli flushdb => Ok

but the error persist.

You should check in file: app/etc/env.php

Look at "Crypt" -> Key have to have 32 characters.

[alexis_turruell]

yes, crypt => key has 32 characters, Whats wrong?
