Siilihai-client Snap Error

Hello;
I wanted to bring to know if anyone can replicate this error after installing the snap of the Siilihai Web Forum client application by Ville Ranki from a Snap downloaded from the Snap Store.

Launching siilihai-client from a Ubuntu 18.04.4 LTS Bash prompt gives this error:

I can not tell if this is siilihai-client natively missing a library or an error in the creation of the Snap.
Upon further investigation, The PPA for this application appears to not have been updated past The Ubuntu Xenial distribution and the PPA is not available when attempting to add the PPA to my software sources:
*Err:41 http://ppa.launchpad.net/ville-ranki/siilihai/ubuntu bionic Release *

  • 404 Not Found [IP: 91.189.95.83 80]*

Thoughts?

On 20.04, I see this:

$ siilihai-client
