This may be as useless as it is obvious, but apparently the upgrade
has been able to download all but the last file successfully, then has
read the last file, but found a mismatch between the expected and
calculated checksum. You might try upgrading from a different mirror,
to see if that problem persists. There should be others relatively nearby,
although they'll probably be in the New England area of the USA. :-)
