Magneto performs a readiness check before installing or updating extensions. If this check fails, it will not allow you to proceed. There are two common reasons for a readiness check failure&mdashincorrectly configured cron tasks and low PHP-FPM memory limits. The PHP-FPM memory limit needs to be set very high, or Magento becomes unstable and will not display error messages.

One-step Repair Script

This script will address both issues. Save the following script on your server as "".

# Move the crontab to the right place
mv -f /var/spool/cron/nginx /var/spool/cron/crontabs/nginx

# Fix PHP memory limit
sed -i -e 's/php_admin_value\[memory_limit\] = 756M/php_admin_value\[memory_limit\] = 2G/' 

# Restart PHP-FPM
systemctl restart php7.0-fpm.service

Run the script.

chmod +x; ./

After the script completes, wait a minute for the cron script to run and then initiate a new readiness check.

Other Issues

There are several other, less common reasons for a readiness check failure. Please refer to the official documentation, which has the latest information.
