Issue: Sophos UTM 9.410 up2date may corrupt boot loader
First Seen: up2date from 9.409 to 9.410
Details: Customers that have installed Sophos UTM 9.409 using Hardware Virtual Machine (HVM) virtualization may corrupt the boot loader during the up2date process to Sophos UTM 9.410. The cause of the issue is the up2date process using the boot loader based on the older Paravirtual (PV) virtualization. Working with AWS, we’ve identified which customers may be affected by this issue and sent those customers an email advising not to upgrade.
Resolution: Our next up2date package will use the correct boot loader for HVM. Target release date is next week. For customers that may have missed the email or accidentally upgraded, you can follow the steps listed in Sophos UTM: How to recover UTM on AWS after updating to 9.410.
