Upgrade to 3.0.1 with error, "No input file specified."

Mautic 2.16.3
PHP 7.2
MariaDB 10.4.14

I am Updating
Upgrading via Web

These errors are showing in the installer :
The file containing the list of deleted files was not found, could not process the deleted file list.

These errors are showing in the upgrade_log.txt file (located in the root of your Mautic instance when an upgrade has been attempted - ensure you remove or redact any sensitive data such as domain names in the file path) :

The file containing the list of deleted files was not found, could not process the deleted file list.

Your problem
My problem is :

Tried many times but kept getting the same error. Attempted to do command line upgrade but was instructed to do it via web only.

Thank you!

Hi,

I don’t recall having a successful upgrade of Mautic using the web interface and the upgrade button. Every time there was something going wrong.
