Issue upgrading Sophos XG Firewall to SFOS 20.0.1 MR1-Build342

Hi 

I having issues with upgrading my Sophos XG Firewall (Home Edition) virtual appliance to SFOS 20.0.1 MR1-Build342 from SFOS 20.0.0 GA-Build222. I can download the firmware via the appliance with no issues, the issue is soon as I press install, webadmin briefly goes down and then returns and there is then two listed firmware's, if I tell it to boot from the new one, it reboots, successfully copies over the configuration from old to new firmware but then it becomes a brick so to speak. It never comes back online, I cant ping, ssh etc to it, it looks fine/normal on console. I have tried manually rebooting it via console, however while doing so I noticed it shows both old and new firmware still as options to boot from. Not sure why this is as I assumed that it would replace the old firmware as part of the upgrade from when you press install, but just looks to swap it over to new and keeps the old still? The other problem is because its in the "bricked" state on the new firmware I can't pull any logs off it to see why its unresponsive and I cannot log in via the console. I am running it on a recent release of Nutanix Community Edition. Has anyone got any suggestions on how I can resolve this so I can upgrade via the appliance? I have tried to upgrade this three times, including rebooting it first before doing the upgrade, oddly the first time I attempted to upgrade it, it rebooted automatically and just went straight into booting into new firmware etc like you'd expect, but since then I've had to do it manually for some reason, followed the same steps as first time.

Many Thanks

  • Hello  , SFOS installs new firmware in the standby slot. so you still have your old firmware as it is and the option to boot new or old firmware. please share console screenshots when a device tries to boot with the new firmware. you mentioned you can't log in via console, does it mean you do not see the password prompt? or password prompt not accepting password? can you please share the error you are seeing while entering password? 

  • Hi  , Thanks for getting back to me. That makes more sense now how the the firmware is updated, I wasn't sure if that was how it was meant to work, thanks for confirming that. I see the password prompt, however it doesn't accept the password I have set, it just comes back as authentication failed, I have tried a few times including trying using the default password of admin, but this doesn't work either. I have attached a screenshot below, which shows both the upgrade process when booting the new firmware for the first time and the password error. Oddly after going back and booting the old firmware, the same console password issue occurs on the old firmware too, not sure why.
