Apt-get error

I just did my normal knoppix hard drive installl and was doing a
apt-get update
apt-get upgrade

when a while through the process i got hit with:


Setting up fontconfig (2.2.0-2) ...
Installing new version of config file /etc/fonts/fonts.conf ...
Installing new version of config file /etc/fonts/fonts.dtd ...
Regenerating fonts cache...done.

Errors were encountered while processing:
locales
E: Sub-process /usr/bin/dpkg returned an error code (1)
root@fearlessrogue:/home/knoppix#

Should I be concerned?
