System Information Ubuntu Version: 22.04 Kernel Version: 5.15.0-57-generic x86_64 PHP Version: 8.0 When setting cron, it is not normally applied. After 10 minutes, the following message is displayed. 'Last background job execution ran 10 minutes ago. Something seems wrong.' Here's how I tried to fix this problem. • Modify crontab crontab -u www-data -e */5 * * * * php -f /var/www/clients/client0/web2/web/cron.php Problem still not resolved. • Add --define apc.enable_cli=1 to cron Problem still not resolved. • Modify apcu.ini Add apc.enable_cli=1 to /etc/php/8.0/mods-available/apuc.ini Problem still not resolved. • Replacing memory caching from APCu to Redis Problem still not resolved. I've tried most of the possible solutions, but the problem hasn't been resolved. Is this a problem because the website owner and group are not www-data:www-data?
