XG Firewall will take longer than previously to upgrade the firmware from v17.5.x to v18 Build_354. This because v18 Build_354 is doing additional checks for file system correction, which would take more time based on the hard disk size and state.
Applies to the following Sophos products and versions Sophos XG Firewall v18 Build_354
Please let the upgrade fully finish and don’t restart the upgrade process in-between, otherwise system could go into undefined state and which will result in a re-image to the appliance with an ISO.
This article will be updated if more information becomes available.
