Upgrade 9.10.2- U2 to U6 doesn't work checksum error

[Asimov1973]

Hi guys,
I was wondering about a message of checksum error when I try to upgrade my NAS in GUI as well when I connect on SSH typing freenas-upgrade check: at 80% it stop saying "cannot upgrade the checksum is invalid"
Someone has an idea ?

I would download the file again and then ensure the checksum MD5 is correct. If it is correct then I would try the manual update. If that fails then I'd ensure you have a copy of your configuration file and just install the ISO of 9.10.2-U6.
