See:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=493095

Did you upgrade apt-get, aptitude, and dpkg before attempting the full
upgrade?  Did you try "aptitude safe-upgrade" as well as "apt-get upgrade"?

Did you try manually upgrading nfs-common, nfs-utils, and mount,
individually, before performing the rest of the upgrade.

Did you attempt any troubleshooting before firing off this email to
debian-user?

As noted in the bug report by one of the devs, they assume a sysadmin
capable of setting up diskless workstations is smart enough to figure
his way around this bug...
