How to upgrade old abi lenny to squeeze

[Tim Froidcoeur <tim.froidcoeur@googlemail.com>]

Hi,

I have an nslu2 which has lenny installed. I don't manage to upgrade it
to squeeze.

apt-get update will complain when pointing /etc/apt/sources.list to squeeze:
" Unable to find expected entry  main/binary-arm/Packages"


> apt-config dump | grep Architecture
APT::Architecture "arm";

I suppose the problem is that this machine still has the old arm abi and
squeeze only supports the new abi.
Is there any alternative to either sticking with lenny or doing a
complete fresh install of squeeze?

thnx

kind regards
