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.
