on your master computer you could run a script somthing like this...

#!/bin/sh

set -e
set -x
ENV="set -e && export TERM=$TERM && . /etc/profile"
UPD="echo && hostname && Updating Package Lists... && apt-get -qq update || true"
UPG="apt-get upgrade --show-upgraded"
UPC="apt-get clean"

for n in host1 host2 hostz; do
 ssh root@$n "$ENV && $UPD ; $UPG && $UPC"
done


don't forget to have ssh-agent working beforehand.
