On June 25, 2019, the Magento version 2.3.2 was released. Improvements to Magento 2.3.2 require installing libsodium cryptographic library version 1.0.13 or higher. Without this you will get an error in the MSP_TwoFactorAuth module.
Missing required argument $encoder of MSP\TwoFactorAuth\Model\UserConfigManager.
So for the successful upgrade, follow these steps:
cd /opt/
wget -c https://download.libsodium.org/libsodium/releases/libsodium-1.0.18.tar.gz
tar -xzvf libsodium-1.0.18.tar.gz
rm libsodium-1.0.18.tar.gz
cd libsodium-1.0.18
./configure
make && make check
make install
composer require magento/product-community-edition 2.3.2 --no-update
composer update
rm -rf var/cache/* var/page_cache/* var/generation/*
php bin/magento setup:upgrade
