I'm trying to upgrade generic-pc-1.235.img to generic-pc-1.3.img. The upgrade appears to go fine and the system reboots automatically as it's supposed to but after the reboot the system page still says:
When upgrading from generic-pc 1.2x, you must install 1.3b7 first before you install this image. Other platforms are not affected. :
