That was it. Thanks Doug! I got overzealous in vim and removed that -O by accident.
I think the official Linux installer should maybe update the instructions to:
curl -L -O http://download.roonlabs.com/builds/roonserver-installer-linuxx64.sh
If I try it in Ubuntu or Fedora without the -L flag it gives me the 301 error code in the screenshot since it has a redirect? I assume the redirect is http to https… so maybe just update the command to be https
FYI, the output:

All Done! RoonServer should be running on your machine now.
