where can i get 'pantheon.list' to go in /etc/apt/sources.list.d?

I have a clean version of lucid.

performed the following:

echo 'APT::Install-Recommends "0";' | sudo tee /etc/apt/apt.conf
sudo wget http://pantheon-storage.chapterthree.com/mercury.list.1.1 -O /etc/apt/sources.list.d/mercury.list
sudo wget http://pantheon-storage.chapterthree.com/aws.list -O /etc/apt/sources.list.d/aws.list
sudo wget http://pantheon-storage.chapterthree.com/lucid -O /etc/apt/preferences.d/lucid
wget http://pantheon-storage.chapterthree.com/gpgkeys.txt -O /tmp/keys.txt
sudo apt-key add /tmp/keys.txt
sudo apt-get update; sudo apt-get -y upgrade; sudo apt-get -y dist-upgrade

from http://groups.drupal.org/node/70268

although had to do:
create a file such as:
/etc/apt/apt.conf.d/11cache
And add the line:

APT::Cache-Limit "32768000";
and changed the

sudo apt-get update; sudo apt-get -y upgrade; sudo apt-get -y dist-upgrade
to
sudo apt-get update && sudo apt-get -y dist-upgrade

After this i then tried running:

apt-get install git-core
git clone git://github.com/pantheon-systems/mercury.git -b master /opt/pantheon
cd /opt/pantheon
python setup.py

but it keeps aborting with the errors:

[localhost] local: curl http://pki.getpantheon.com | sudo tee /usr/share/ca-certificates/pantheon.crt
/bin/sh: curl: not found
[localhost] local: echo "pantheon.crt" | sudo tee -a /etc/ca-certificates.conf

cp: cannot stat `apt.pantheon.list': No such file or directory

Fatal error: local() encountered an error (return code 1) while executing 'cp apt.pantheon.list /etc/apt/sources.list.d/pantheon.list'

Then just as a test I tried adding it manually as above with:

sudo wget http://pantheon-storage.chapterthree.com/pantheon.list -O /etc/apt/sources.list.d/pantheon.list

but its forbidden.

What could be the issue that means this file isn't being setup properly?

Much appreciated!
