freebsd-update; What did I do?

[Martin McCormick]

	I started to run freebsd-update to upgrade a 8.x system
to 9.0-RELEASE

# freebsd-update -r 9.0-RELEASE upgrade

Looking up update.FreeBSD.org mirrors... 4 mirrors found.
Fetching metadata signature for 8.2-RELEASE from update5.FreeBSD.org... done.
Fetching metadata index... done.
Inspecting system... done.

The following components of FreeBSD seem to be installed:
kernel/generic src/base src/bin src/cddl src/contrib src/crypto src/etc
src/games src/gnu src/include src/krb5 src/lib src/libexec src/release
src/rescue src/sbin src/secure src/share src/sys src/tools src/ubin
src/usbin world/base world/dict world/doc world/info world/manpages
world/proflibs

The following components of FreeBSD do not seem to be installed:
world/catpages world/games world/lib32

Does this look reasonable (y/n)? yes

Fetching metadata signature for 9.0-RELEASE from update5.FreeBSD.org... done.
Fetching metadata index... done.

The update metadata is correctly signed, but
failed an integrity check.
Cowardly refusing to proceed any further.

	What is the next step, here?

Thank you.
