The APCu backend cannot be used because apcu is disabled on CLI

[ TYPO3\CMS\Core\Cache\Exception ]
#1232985915: The APCu backend cannot be used because apcu is disabled on CLI.
thrown in file typo3/sysext/core/Classes/Cache/Backend/ApcuBackend.php
in line 84

This error occurs if TYPO3 is executed in command line context. The reason is, that typo3conf/LocalConfiguration.php uses TYPO3\\CMS\\Core\\Cache\\Backend\\ApcuBackend as caching backend, which works fine if called using an HTTP-context (e.g. via Apache or nginx) but does not if invoked via CLI (command line interface).

Solutions

Change Cache Backend: Goto TYPO3 Install Tool --> Configuration Presets and choose Database cache backend (or: something different then apcu) and save.
Adjust PHP CLI configuration to fix this behavior: modify configuration file /etc/php/7.1/cli/conf.d/20-apcu.ini (as an example on Ubuntu 17.10) and add new setting apc.enable_cli=on
