Not sure if anyone else has seen this issue, but I had the same issue trying to upgrade from 1.400 to 1.401 that others reported when trying to upgrade from 1.300 to 1.301:
[12]: system operation (install System Up2Date) failed execution
[1.300]Can't upgrade to 1.301 via Webadmin
I logged into the machine as root and ran this as suggested in the thread:
auisys.plx --configfile /etc/up2date.conf --level i
And the machine rebooted, everything seems to have been applied OK.
