I'm probably doing something wrong, but I've run the debain generic installer script and it has put the correct source references in `/etc/apt/sources.list.d/Flirc_repo.list`. I'm on jessie, so the entries look like:

deb-src https://packagecloud.io/Flirc/repo/debian/ jessie main

So far so good. Nothing gets loaded though. apt-get update reports:

Ign https://packagecloud.io jessie/main Translation-en

Looking at packagecloud, there is no listing for jessie related packages.

Where do I go from here?

Just change it manually to:
deb https://packagecloud.io/Flirc/repo/ubuntu/ zesty main

The packages should all be the same anyway.

Ah, yes. It had to be something like that :) Installed and running. Thanks.
