Errors

Memcache \OC\Memcache\APCu not available for local cache

/etc/php/7.4/mods-available/apcu.ini

apc.enable_cli=1

The PHP memory limit is below the recommended value of 512MB

/etc/php/7.4/apache2/php.ini

memory_limit = 512M

A memcache is not required and you may safely ignore the warning if you prefer

config/config.php
