After an upgrade to the latest libc6, I get the following behavior when
doing an `apt-get update`:

This happened after an update to the following packages (dump from
apt-get -u):
base-config base-files console-common debconf debconf-i18n diff
findutils iptables libc6 login modutils nano passwd ppp procps
proftpd proftpd-common proftpd-doc pump wget wwwconfig-common
I unfortunately do not know which version of libc6 I was running prior
to this update.
