Magento – Cron error extension – Magento2

I ran into the same issue today. It appeared that the app/etc/env.php was missing. This means that Magento was not yet installed. During Magento installation it will create this file, so:

• make sure app/etc/ is writable for the magento user/webuser
• run bin/magento setup:install ...params...

In my case, some script that I made was not copying my env.php file into the app/etc/ folder.

It is also possible that the file is there, but it is not readable for the Magento user/webuser.

This is mainly to help others suffering with the same issue. This is what I have discovered.

There are 2 versions of Magento, the Magento download package which comes with composer installed and Magento from Github where you need to install composer.

The file path above wasn't there and doesn't need to be there because those files are stored under vendor.

My issue was mainly relating to the .setup_cronjob_status & .update_cronjob_status files under /var/ these are created on cron and store info.

It seems these store cache info. On deleting those files and all files under pub/static solved my issue.

I hope that helps someone else.
