I have the KVM version of sothis XG v18 EAP3.
I get the notification update (VIKM-18.0.0_EAP3-Refresh1.KVM-285) from the Sophos XG interface, I click on download, install... and then I get this error
New firmware could not be uploaded. Please refer to online help for possible reasons
And this is why I get in the logs
Firware Installation failed because of Appliance version mismatch
How can be a mismatch If I am downloading it from the Sophos interface?
