Magento2 not executing InstallSchema.php or UpgradeSchema.php

I've created a custom module, and I see the row in the setup_module table. When I change my version and run magento setup:upgrade, the version number updates as well. However, the table I defined is not being created. I also see the new module enabled in app/etc/config.php

I tried installing a module written by Magento, but I still see the same behavior - row is in setup_module but table does not exist.

I tried deleting the row from setup_module table and rerun magento setup:upgrade to execute InstallSchema.php, but the database tables aren't created even though the row is created setup_module again.

I also tried incrementing the version number and try UpgradeSchema.php, but it doesn't execute even though row in setup_module is updated.

I introduced errors in both InstallSchema.php and UpgradeSchema.php, but magento setup:upgrade doesn't does not output the error messages.

I also tried recreating the installation, and ensuring the file permissions were correct (owned by magento:www-data). Any other ideas?

I'm using v2.0.7 CE provided by DigitalOcean.
