Install script does not indicate that Cosmic is not yet supported

[austinorth]

I'm running Ubuntu MATE 18.10 (Cosmic) and tried the installation instructions from http://www.soundnodeapp.com/#download with the following results:

$ curl -s https://packagecloud.io/install/repositories/JonasGroeger/soundnode/script.deb.sh | sudo bash
Detected operating system as Ubuntu/cosmic.
Checking for curl...

followed by

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

and then

$ sudo apt-get install soundnode

E: Unable to locate package soundnode

Assuming this is because Cosmic is not yet supported, but could not find an issue anywhere mentioning this specifically, so figured I'd post this. If a release of a Cosmic version is imminent, I understand why a tweak to the script would be unnecessary, and I'll probably just build from source as a workaround for now, so definitely not a high priority issue (for me at least)!

I'm having the same problem with 18.04 Bionic.
I don't know why, but it keeps on detecting my install as "elementary/juno". Probably because I have Pantheon installed.
