SOLVED: jellyfin.service is masked

[WhatsTheDealio]

Thanks for the suggestion, but it unfortunately didn't fix it.

I did a remove of the previous attempt, and tried curl:

$ curl -s https://repo.jellyfin.org/install-debuntu.sh | sudo bash

After that, I did a restart all daemons as requested. Then tried starting the service. I still get:
Failed to start jellyfin.service: Unit jellyfin.service is masked.
