404 Not Found on wget commands; invalid reference format: repository name must be lowercase in singularity commands

Using the tutorial on the LBPM page on RHEL 8, all of the wget comments to build the Singularity container fail with:

Also see errors when running this command:

singularity version 3.7.1

I'm looking into this issue. Can you confirm if you are authenticated to the NGC container repo or are you accessing as a guest?

As a guest, which is probably a big part of the problem. I see sample instructions to login but unfortunately we don't use Docker (the whole needing to be root thing), so I can't invoke a docker command to login at the CLI. I was able to find the 3 files and download them but the singularity command fails with the above error.
