Cannot upgrade a T10 from 12.5 to 12.5 Update 1
That dang lack of memory is back to haunt me.
It won't upgrade from PM nor from the web UI by direct download from WatchGuard nor by T10.sysa-dl file, even after a reboot.
Trying to upgrade from the web UI, I got this error:
An error occurred in the upgrade process: 161 Backup failed: Reserve RAM failed. Please run the backup when system load is lower. Upgrade canceled. No changes were made to the Firebox.
What magical steps must one take to get a T10 to upgrade?
