JSON feed for linuxunplugged.com is invalid

[RealOrangeOne]

Previously, linuxunplugged.com/json emitted a JSON feed. At some point recently, this stopped being true, and instead it redirects to feeds.jupiterbroadcasting.com/lup, which is an XML RSS feed. This makes sense as a redirect target for linuxunplugged.com/rss, but not for /json`.

The other show feeds all work fine, it's just LUP.

I don't have access to Fireside to properly suggest why this changed and what we need to change to get the JSON feed back.

Because one feed fails, this means the entire site isn't being updated correctly.
