Autoupgrade firmware for expired support

[chrisgdg]

My Fortigate device is out of support, and is currently running 7.4.8.

It has started to attempt upgrading to the latest patch (7.4.9) as per the new upgrade mechanism:

https://docs.fortinet.com/document/fortigate/7.4.0/new-features/320693/automatic-firmware-upgrades-f...

However it keeps failing and sending emails that it has failed.

logdesc="A federated upgrade could not be completed by the root FortiGate" msg="Federated upgrade failed after reaching state downloading" reason="download failed"

Its sent that one a few times, is now also sendning emails regarding the schedule being changed:

logdesc="Automatic firmware upgrade schedule changed" user="system" msg="System patch-level auto-upgrade new image installation (re)scheduled to between local time Thu Oct 23 01:42:23 2025 and local time Thu Oct 23 04:00:00 2025. This installation is forced and cannot be cancelled."

Does anyone know how I can fix it so it is abel to upgrade it, or to disable the upgrades that keep erroring?

Many Thanks,

Chris

I'm having the same exact issue, download failed. No other way to update.
