OMSA for Ubuntu

Hi,
I have been trying to install omsa on Ubuntu (trusty) using the procedure described here:
http://linux.dell.com/repo/community/ubuntu/

apt-get fails with:
W: Failed to fetch http://linux.dell.com/repo/community/ubuntu/dists/trusty/openmanage/binary-amd64/Packages 403  Forbidden
W: Failed to fetch http://linux.dell.com/repo/community/ubuntu/dists/trusty/openmanage/binary-i386/Packages 403  Forbidden
E: Some index files failed to download. They have been ignored, or old ones used instead.

Normal ubuntu repos all work fine and I can access files directly with wget

Any ideas welcome

-Lawrence
