I've been trying to set up 2 810 cores, but during the pre-install-from-repo.sh script it gets package errors.
First it has trouble when fetching sources:
W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/intrepid-updates/restricted/source/Sources.gz 500 Server reports illegal range
Err http://au.archive.ubuntu.com intrepid-updates/restricted Translation-en_AU Could not connect to localhost:3142 (127.0.0.1). - connect (111 Connection refused)
W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/intrepid/restricted/il8n/Translation-en_AU.bz2 Could not connect to localhost:3142 (127.0.0.1). - connect (111 connection refused)
W: Some index files failed to download, they have been ignored, or old ones used instead.
These are just an example, there same error is coming up on a dozen different ones & obviously the packages the script tries to install fails.
It also does it on a manual apt-get dist-upgrade, but only after running the pre-install-from-repo script the first time.
